BP Tauri

BP Tauri is a young T Tauri star in the constellation of Taurus about $$ away, belonging to the Taurus Molecular Cloud.

Properties
BP Tauri is still accreting mass at the low rate of $$ and $$/year, as evidenced by X-rays produced by infalling matter, and may be still in the process of spin-up. Its chromospheric magnetic fields are rather strong at 2.5$$ kilogauss, and contains strong non-dipole components. The star is producing 40% of its luminosity via the energy released by accretion.

Suspected companions
There were two suspected stellar companions to BP Tauri on projected separations 3.00 and $$. These were proven to be a background stars not related to BP Tauri with Gaia data though.

Protoplanetary system
The star is surrounded by a protoplanetary disk. The disk is strongly depleted in carbon and carbon monoxide.

Variability
BP Tauri varies in brightness, producing a strong flares due to unsteady accretion held by stellar magnetic field. The lightcurve period is variable from 6.1 to 7.6 days, and quiescent periods without variability are also known.
