GK Tauri is a young binary system composed of T Tauri-type pre-main sequence stars in the constellation of Taurus about Шаблон:Val away, belonging to the Taurus Molecular Cloud.

System

The stars GV Tauri A (GV Tauri S) and G Tauri B (GV Tauri N) form a wide binary system, with the projected separation between components being 170 AU. Both are strongly shrouded by circumstellar dust - GV Tauri A by 30 magnitudes and the GV Tauri B up to 59 magnitudes in the V band.[1] Both components are suspected to be binaries themselves,[2] as they produce strongly ionized jets and molecular outflows.[3]

Properties

Both members of the binary system are medium-mass objects still contracting towards the main sequence and accreting mass, although accretion rates remain highly uncertain as of 2009.[1]

Protoplanetary system

Both stars are surrounded by protoplanetary disks, with the observable dust in each being about Шаблон:Val Шаблон:Solar mass, and the gas about 0.005 Шаблон:Solar mass.[4] The disk of GV Tauri B is rich in carbon monoxide, hydrogen cyanide and, unusually, methane.[3]
