Candidate eruptive young stars in Lynds 1340
Listed in IVOA Registry (Virtual Observatory)
We report on the discovery of three candidate eruptive young stars, found during our comprehensive multi-wavelength study of the young stellar population of the dark cloud L1340.
Description
These stars are as follows. (1) IRAS 02224+7227 (2MASS 02270555+7241167, HH 487S) exhibited FUor-like spectrum in our low-resolution optical spectra.
The available photometric data restrict its luminosity to 23L_{sun}_<L_bol_<59L_{sun}_. (2) 2MASS 02263797+7304575, identified as a classical T Tauri star during our H{alpha} survey, exhibited an EXor-type brightening in 2005 November at the time of the Sloan Digital Sky Survey observations of the region. (3) 2MASSJ02325605+7246055, a low-mass embedded young star, associated with a fan-shaped infrared nebula, underwent an outburst between the DSS 1 and DSS 2 surveys, leading to the appearance of a faint optical nebula.

Our [SII] and H{alpha} images, as well as the Spitzer Infrared Array Camera 4.5{mu}m images, revealed Herbig-Haro objects associated with this star. Our results suggest that amplitudes and timescales of outbursts do not necessarily correlate with the evolutionary stage of the stars.
