No. They have the lowest temperatures on the main sequence. The hottest main sequence stars are blue.
Blue
Blue stars have the highest surface temperature, at over 7,500 Kelvin. The surface temperature of red stars is less than 5,000 Kelvin.
Red stars have the coolest surface temperature. Blue color stars have the highest surface temperature. The Sun belongs to the main sequence stars.
Red stars have the coolest surface temperature while blue stars have the highest surface temperature. NERD!
The star with the highest surface temperature is the blue star called O-type stars. These stars can have surface temperatures exceeding 50,000 degrees Celsius.
as surface temperature increases, luminosity increases
The smallest stars in the main sequence are the stars with cooler surface temperatures.
Sirius A and Procyon A are two stars that have similar luminosity and surface temperature. They are both main-sequence stars and are relatively close to each other in terms of these characteristics.
Absolute magnitude and surface temperature
The hotter the star, the brighter. Ex: A stove
The temperature of main sequence stars can vary quite a bit.
They are defined by their absolute magnitude and surface temperature.
