According to a study, there may be a whole new class of black holes that scientists were not aware of.
A study published Thursday in Science found a new way for astronomers to search for black holes and that there may be a whole group of black holes smaller than the smallest black holes in the universe.
"We show this hint that there is another population that does not yet need to be explored in the search for black holes," says Todd Thompson, in a statement, a professor of astronomy at Ohio State University and lead author of the study.
"People try to understand the explosions of supernovae, how supermassive black stars explode, how the elements form supermassive stars. So if we could uncover a new population of black holes, it would tell us more about which stars explode, which ones don't, which form black holes that form neutron stars. This opens up a new area of study, "he added.

RESTORING THE SEA LEVELS, IT CAN STOP 19659003] Thompson said that one way to understand the survey was to imagine if the city counted only people 5 & 9 "and above in its census – and imagine if those census workers didn't even know that there are people less than 5 & # 39; 9 ". That data would be incomplete, he said.
Black holes last for a long time, forming when some stars die, shrink, and collapse, for many years researchers believe that black holes exist only in a certain range of masses.
his colleagues began searching for data from APOGEE, the Apache Point Observatory's galactic experiment, looking for stars to show change, and after narrowing the data to 200 stars, they found a giant red star orbiting something unknown, based on their calculations it was probably a black hole with a low mass of about 3.3. times the mass of the sun.
"What we have done here is inventing a new way to search for black holes, but we have also potentially identified one of the first of a new class of low-mass black holes that astronomers didn't know about until now. "The masses tell us about their formation and evolution, and they tell us about their nature."
