V433 Aurigae
V433 Aurigae is a young, bright star in the constellation Auriga. It is a slowly pulsating B-type star, so its brightness varies very slightly as it pulsates. The changes are only a few hundredths of a magnitude every about 4.6 days, and under very dark skies it can be seen with the naked eye.
The star shines about 14,000 times brighter than the Sun and has a surface temperature around 17,000 K. It has roughly 8.7 solar masses and a radius near 9.8 solar radii, with a surface gravity (log g) around 3.24. It sits about 3,200 light-years away from us.
V433 Aurigae moves at about +23 km/s relative to the Sun and has a small apparent motion across the sky. Its parallax is about 1.01 milliarcseconds, supporting the estimated distance. The star is roughly 20 million years old.
Other names for V433 Aurigae include HD 37367, HIP 26606, HR 1924, and BD+29 947. It was identified as a variable star from Hipparcos data, with the variable designation assigned in 1999.
