V830 Tauri is a T Tauri star located 425.2 light-years (130.4pc) away from the Sun in the constellation Taurus.[6] This star is very young, with an age of only 2 million years,[6][7] compared to the Sun's age, which is 4.6 billion years. Typical for a young star, it exhibits strong flare activity, with three flares detected during a 91-day observation period in 2016.[8]
Characteristics
V830 Tauri is an M-type star.[6] The star has a mass of roughly 1 solar mass, but has a radius of 2 solar radii,[6][7] due to the star's age, which means that it hasn't fully contracted yet to become a main-sequence star. (It will likely be on the main sequence portion of its lifetime for about 10 billion years, much like the Sun.) It has a surface temperature of 4,250K.[6][7] For comparison, the Sun's surface temperature is 5,772K.
V830 Tauri is a weak-lined T Tauri star, a pre-main sequence star that has a surrounding disc producing emission lines in its spectrum.[4] It is also classified as a BY Draconis variable, cool stars with starspots and chromospheric activity that vary in brightness as they rotate.[3] The variable period of 2.74 days matches the rotation period.[4]
