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

System

The stars GK Tauri and GI Tauri form a wide binary system, with the projected separation between components being 1700 AU. The secondary component's orbit is not very eccentric, with a periastron of at least 890 AU.[1]

GK Tauri was originally believed to have a close stellar companion WDS J04336+2421Ab.[2] However, it was found to be an unrelated background star according to Gaia data.[3]

Properties

Both members of the binary system are medium-mass objects still contracting towards the main sequence and accreting mass, with the primary GK Tauri being close to entering the main sequence.[4][1]

Protoplanetary system

Both stars are surrounded by compact protoplanetary disks, although the reason for the small disk sizes is not clear.[1] GK Tauri's spectrum indicates a possible gap in the protoplanetary disk and a planet orbiting within the gap, with a semimajor axis of 2.4Шаблон:± AU.[4] Шаблон:OrbitboxPlanet begin Шаблон:OrbitboxPlanet disk Шаблон:Orbitbox end
