Mappings in the mapped star can solve a deep cosmic mystery

I don’t think it’s an extra poet to say that the stars are how we know the universe.

If we look at the sky at night, the stars are more we see – Thousands, from Sirius, the worst of the nightmares instead of the catalog names instead of the catalog names.

And for every star we see in the eyes of our heaven, Telescopes can see millions more. Astronomers study them to understand the form, size, structureHistory, and fate In our galaxy and used it to determine the distances and behavior of other galaxies. Even if the exoplanets are studied, We need to understand their host stars to understand foreign worlds. The more serious elements that make our planet and even our body forced by the stars In the past, and our own day is a star, of course – in real sense, studying stars is to study ourselves.

However for all, some basic questions about stars remain unanswered. As we have a great awareness of how individual stars are born, there are gaps in our knowledge of their statistics more.

One of my favorite questions that did not answer the most important assets of the stars as a group, which kind of different types of a cotton cloud. Say you have A giant cracked pork those stars to make a waterfall. As a percentage, how many of them would be like the sun? How much to be weak red dwarfs, how many blue animals can be, and How much can be too low in the masses they wear the line between a real star and a planet? The mass of a star – what is important to this – determines most of its properties, including temperatures, color, light, light, evolution and evolution and evolution and evolution Even its destinySo this is something that is very astronomers to understand. The distribution of stars of the stars of our galaxy tells us about galaxy, such as bringing the contents of a construction offering views about the finished product and how it gathered.

The “initial function of the mass” is the technical term for unresolved stellar demographic questions. And in theory, less difficult to answer: observe just a set of stars, know their masses and then figuratively put it in the right box.

Instead, in practice, very difficult. The massive stars are bright and easy to see. However, we can’t look at the little, dims when they are too far – which means our cosmic census of the stars lower than our solar system. However given time, these stars mix well with the whole galaxy, so we can find out such scholars in Seinter Shopllar Sie-door sidlaric sieor sidlaric sie-poor sek-poor recedivation SA Gaalxy.

However, to give you an idea of ​​how difficult this activity is, after the Millennia of astronomical observations, the first to complete only 65 years have shown – at 2024! Published by a large team of astronomers, paper, which Published to Astrophysical Journal,, a developmental description of Herculean effort involved.

The conduct of the survey in the first place required using multiple spaces – and astronomical astronomical observations. Milky Waycy Way’s Milcy Way-Mapping Gaia Mission is a stem among them, and it targets key data for most bright stars within the required 65 years of light. For mass stars radically, shining in infrared, Gaia’s observations extends data from the NASA’s width and the Spitzer Space Telescope.

Such stellar dimbs bulbs are critical for determining the lowest passage at the end of the first mass movement. Brown dwarfs, things with intermediate masses between planets and starsProvide significant invisible light and can only be seen in infrared. The first brown dwarfs were found only in the 1990s. And generally, these things are more decaying that even adjacent to the detection of detection. Luhman 16 A Binary Brown Dwarf System 6.5 only years the day from Sun-the third nearest system to us-Anet found only in 2013.

After carefully rejected the details of the goods confirmed within 65 light-year region, the study team was found to be nearly 3,000 stars and 600 brown dwarfs. Immediately this is a unique search. I’m used to thinking of greater spatial scales, so Find 3,600 items within only 65 years of day more than I know. Think of you, our Milky Way Galaxy is a flat disk 120,000 light-to-across, large enough for Hundreds of billions of stars and other citizens of heaven.

Consider astronomers to note that their survey is incomplete at the end of Mass-Mass. Brown dwarfs coolers than about 325 degrees Celsius very smiling that our current technology does not directly see them over 50 light-time. As well as, some more brown dwarfs can still hide many parts of the sky, such as the Galaxy Star-Rich disk. Can also be small binary partners with some stars unknown.

Meaning is that some brown dwarfs are likely to be covered, which is actually trouble trying to determine the whole masses of gases that change galactic gas clouds. Think about it that way: If you break a stone with a hammer, you’ll probably get one or two big pieces, a dozen chunks and thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands or thousands of small grains. If you don’t count all grains, you don’t know how the size of the debris is distributed.

However, this new, best census in our interstellar neighborhoods gives our understanding of the first mass movement. Before, it’s not clear when things have a mass cut at the lower end. We know that gas clouds at stellar nursery should form clumps crumbled under their own gravity and that these clumps become stars. Is there a limit on how small a clump can crumble? Perhaps, but until discovered and counts the brown dwarfs and counted, we are not sure they can still be the stars. The foundation of the census is that the number of items formed mainly increases as the mass decreases, as expected, such as garbage distribution from a hammer beaten stone. But the census reveals some quirks: Tally of things flattened a little while the masses come from steellar masses to brown dwarfs but then start again. Does it repeat some lower mass, like a few moments in jupiter? That is for future telescopes to find out.

However this survey is a big step forward. Milky Way Extrauing and other galaxies help us understand how galaxies behave – and how they change their behavior to many stars of their age. The confidence that is in our knowledge of science depends on every link of the chain, so we better know the initial setting of the masses, the more we understand the universe.
