Photometric and spectroscopic study of the burst-like brightening of two Gaia-alerted young stellar objects

Zsófia Nagy, Péter Ábrahám, Ágnes Kóspál +18

Young stars show variability on different time-scales from hours to decades, with a range of amplitudes. We studied two young stars, which triggered the Gaia Science Alerts system…

Recurrent strong outbursts of an EXor-like young eruptive star Gaia20eae

Fernando Cruz-Sáenz de Miera, Ágnes Kóspál, Péter Ábrahám +21

We present follow-up photometric and spectroscopic observations, and subsequent analysis of Gaia20eae. This source triggered photometric alerts during 2020 after showing a 3…

A WC/WO star exploding within an expanding carbon-oxygen-neon nebula

A. Gal-Yam, R. Bruch, S. Schulze +46

The final explosive fate of massive stars, and the nature of the compact remnants they leave behind (black holes and neutron stars), are major open questions in astrophysics. Many…

Physical parameters of red supergiants in dwarf irregular galaxies in the Local Group

N. E. Britavskiy, A. Z. Bonanos, A. Herrero +6

Increasing the statistics of evolved massive stars in the Local Group enables investigating their evolution at different metallicities. During the late stages of stellar evolution,…

An UXor among FUors: extinction related brightness variations of the young eruptive star V582 Aur

P. Ábrahám, Á. Kóspál, M. Kun +24

V582 Aur is an FU Ori-type young eruptive star in outburst since 1985. The eruption is currently in a relatively constant plateau phase, with photometric and spectroscopic va…

Monitoring luminous yellow massive stars in M33: new yellow hypergiant candidates

M. Kourniotis, A. Z. Bonanos, W. Yuan +3

The evolution of massive stars surviving the red supergiant (RSG) stage remains unexplored due to the rarity of such objects. The yellow hypergiants (YHGs) appear to be the warm co…
