Title: The star formation environment of V582 Aur
Author: Maria Kun, Elza Szegedi-Elek, Bo Reipurth

We have studied the environment of the FU Ori type star V582 Aur. Our aim is to explore the star-forming region associated with this young eruptive star. Using slitless spectroscopy we searched for H alpha emission stars within a field of 11.5arcmin x 11.5arcmin, centred on V582 Aur. Based on UKIDSS and Spitzer Space Telescope data we further selected infrared-excess young stellar object candidates. In all, we identified 68 candidate low-mass young stars, 16 of which exhibited H alpha emission in the slitless spectroscopic images. The colour-magnitude diagram of the selected objects, based on IPHAS data, suggests that they are low-mass pre-main-sequence stars associated with the Aur OB 1 association, located at a distance of 1.3 kpc from the Sun. The bright-rimmed globules in the local environment of V582~Aur probably belong to the dark cloud LDN~1516. Our results suggest that star formation in these globules might have been triggered by the radiation field of a few hot members of Aur OB 1. The bolometric luminosity of V582 Aur, based on archival photometric data and on the adopted distance, is 150-320 Lsun.

Title: The FUor Candidate V582 Aurigae: First Photometric and Spectroscopic Observations
Authors: Evgeni Semkov, Stoyanka Peneva, Michel Dennefeld

One of the most attractive events in the pre-main sequence evolution is the FU Orionis (FUor) outburst. Because only a small number of FUor stars have been detected to date, photometric and spectral studies of every new object are of great interest. Recently, a new FUor candidate was discovered by Anton Khruslov - V582 Aur. To confirm the FUors nature of this object we started regular photometric observations with the telescopes of the National Astronomical Observatory Rozhen (Bulgaria). A high-resolution spectrum of V582 Aur was obtained with the 1.93 m telescope in Haute-Provence Observatory (France).
