What stars are called infrared?
| September 19, 2020 | Education
In principle, any star has infrared radiation, but in astronomy, infrared stars are understood as stars that emit the bulk of their energy in the range of 0.74 – 2 micrometers. Most of the found IR stars belong to long-period variable stars with temperatures of 1500 – 3000 K. However, there are IR stars emitting in the far infrared region (n> 4 μm). It is assumed that the gas-dust envelope surrounding the star is responsible for such radiation.
