We live in the Milky Way galaxy. That is correct. Because that is the exact location of our earth, this time milky way galaxy made the path to another reveal. We are here to see that. I think you will get more details about that star. Even I like to say about the information about the star and as well as about the milky way. But before that, we have to see what is the above star and what are the features. Shall we start now????
Do you know the instrument that helped to reveal this? That is a famous instrument. You know about that already. That is TESS. Can you remember that?? Or else that above would be identified as Transiting exponent survey satellites. That instrument shows the story of such a star. Plus it shows the age of the above natural object.
There is a specific name for that above star. That has to be named as the indi. The name is because of some speciality. The name indi comes with the Indus constellation. The above star is placed in the above constellation. According to the details of the TESS, this star has an age of 11.5 billion years.
Other than the TESS the Gaia telescope is showed some characteristics of the above star. Especially about the motion or the rotation of the above star. Through the details of Gaia, it can have an idea of the changing of the rotation of the above star. That changed its rotation after the galactic collision. That is the idea of scientists.
Now they have found out the birthplace of the V indi star. That is in a milky way. The exact place is the halo of the Milky Way. Or else gassy fringe. The age of the star can have in the range of 11.6 billion and 13.2 billion years. The research came in front of the public recently. That was on the 13th of January. That was at the journal Nature Astronomy.
These above are details of the research. Then we will see more about the above star, TESS and the Gaia telescope. First of all, we’ll see about TESS or the Transiting Exoplanet Survey Satellite.
TESS or the Transiting Exoplanet Survey Satellite
That is using as a space explorer. Plus you know that this is the next device assigned for the Kepler’s task. I think that TESS is a suitable device to perform Kepler activities. On the 18th of April 2018, the TESS was launched. That was planned to find out about more than 20,000. More than 20,000 of exoplanets. Until now TESS had identified about 1400 exoplanets.
On the 7th of August 2018, the first image was taken. Then on the 17th of September 2018 that was released publicly. The space observatory is the mission type. The foundation of this TESS is NASA. This was planned for two years. The planned region is the higher earth. The eccentricity level is 0.55. TESS provides facilities to find out about the planets similar to the earth by the transit method. Through this, 400 times of space can be covered than the Kepler.
The main objective is the above mission is to find about the brightest natural object in the sky. The mass, size, and the density of a planet can be observed with this instrument. There is another portion of this telescope. That is the James Webb space telescope. Through this, the primary targets of the space.
TESS is using a different path. That is the elliptical orbit. TESS orbits two times when the moon revolves only one time.
TESS started the work officially on the 25th of July 2018. There is another thing that is depicted by TESS observations. That is the Alpha Draconis. The alpha Draconis is a type of star. Through the data by the TESS, the alpha Draconis can be concluded that eclipsing binary star.
You know there is a ground system by the TESS. It was divided among the eight sites. Those are divided among the United States of America.
Then we have to talk about the payloads of the TESS. Some of them are as follows. There are four CCD cameras. Those are very powerful as to image the space. Within the time period of the investigation, TESS will examine both the northern and the southern parts of the earth. I mean about the southern hemisphere and the northern hemisphere. TESS had completed the first part of its investigation at the end of July. After the 60 days, the planners decided to start the primary mission.
Those are the main details about the project of TESS and the about the satellite. Those are enough for you now.
Then we will see about the other one that helps you most to discover about the above star. Then I thought to tell you something about the star as well because we have to see a star.
What is a star??
Mainly stars are formed with the dust particles in the outer space. Stars are very bright in the night sky. Do you know the reason to be bright that stars??? The reason is thermonuclear fusion. They are as bright as the full moon. They are not regular, but sometimes it can be.
That takes place with the hydrogen and helium. How that star is making ?? I mean the start of life. That is because of the gravitational collapse. That is taking place at the nebula. That nebula is composed of some gases. Those gases are such as helium and hydrogen. Stars are divided into the constellations. You can identify them very easily because of that
Do you know the star systems?? They are the binary star system and the multi-star system. With the collection of stars, there can make a huge structure. That is the star clusters. Or else that can be a galaxy.
Then this is the right time to move on with the Gaia telescope. That is such a helpful instrument.
Gaia is a spacecraft by the European space agency. About 2013 this spacecraft was launched. And scientists expect to operate this until 2022. That spacecraft designed for various tasks. I decided to tell you some of them. That was designed for the astronomy, distance and the motion of the stars in space and measuring the positions. The last aim from this mission to make the largest 3D space catalogue. And to examine approximately about 1 billion stars.
The Gaia spacecraft is included to the astrometric observatory. There are exceptional payloads are here. Some of them are the astrometric instrument, photometric instruments and radial velocity spectrometer.
There is another speciality of this spacecraft. That is, it will examine its targets for about 70 times. That is essential to determine the exact places of the stars. Already you know about the three-dimensional map. That is including the descriptive details of the luminosity, effective temperature and the gravity of the elements.
In the future, there will be another project introduced. GaiaNIR is a future proposed project. With this project, the project can be widened. Here the GaiaNIR means the Gaia near the infrared. That means this project can be done with the infrared rays. Therefore some natural objects can be detected with the infrared rays. Those objects cannot be detected normally.
Then we had seen about the above main star. That is v indi star. Can you remember that in the above I told you the founded details about v indi star? Therefore now we will pay our attention towards the star constellation of the above star.
About the constellation…
In the above, I told you revealed details about the v indi. You can read about the Indus constellation from here. This is situated in the Southern part of the sky. I think you already know that because I told you.
As for the initial time, European people investigated the above constellation. Pieter Platevoet mapped the Indus constellation. There are about three main stars in the constellation. I mean the known main stars. Out of the Persian is the brightest star. This is not alone. Because there are constellation friends for the above Indus constellation, some of them are paved, octans, grus and Sagittarius. I think you have got my idea. I said about the surrounding constellations.
Here there is no star ranked as the highest glowing star in all galaxies including ours. Out of them, no star hasn’t come to the top 100 list even. Alpha indi, beta indi and delta indi are some of the stars in the Indus constellation. According to some discoveries of the Indus constellation, those above three considered as the highest glowing stars. These above stars are placed as a right Angled triangle in the space.
Not only the above three. Among the stars of the Indus constellation, the nearest star to the earth is Epsilon indi. The distance is approximately about 11.8 light-years. Theta indi is a binary star in the Indus constellation. That is very far from us or our planet. The distance from us is about 97 light-years. T indi is the highest glowing star in the above constellation. That is also a variable glowing star. I am correct if I tell it as only the variable bright star except that this is a red giant.
Not only the stars but also some galaxies are included in the above star constellation. I can give the names of them. They are NGC 7049 and NGC 7090.
Then I have come to the end of this article today. I think I told you interesting details about the above topics. I like if you get some use through my words. Like the above one in the future, you can know some more.
