The curved jet in the young star FN Tau

Solar and Stellar Astrophysics 2026-04-23 v1

Abstract

In the vicinity of the young star FN Tau, we have detected a microjet and four Herbig-Haro objects, whose positions and kinematics indicate the presence of a bipolar collimated outflow from the star - HH 1267. The stellar jet does not propagate rectilinearly, and we discuss the possibility that the curved shape of the jet, whose axis is inclined to the line of sight at an angle <20<20^\circ, results from the precession of the inner regions of the FN Tau protoplanetary disk. Approximately 60 years ago, the star underwent outbursts with an amplitude of Δmpg2m\Delta m_{\rm pg} \sim 2^{\rm m} lasting several months, which we associate with the onset of the microjet.
