Chemical abundances of the young inner-disk open cluster NGC 6705 observed by APOGEE: sodium-rich and not -enhanced
V. Loaiza-Tacuri, K. Cunha, D. Souto +19
Previous results in the literature have found the young inner-disk open cluster NGC 6705 to be mildly -enhanced. We examined this possibility via an independent chemical abundan…
Confirmation of the star J004229.87+410551.8 in M31 as a B[e] supergiant
Sarkisyan A., Vinokurov A., Solovyeva Yu. +4
We study the luminous blue variable candidate J004229.87+410551.8 in the Andromeda Galaxy. Earlier, the star displayed a spectral anomaly: although a hot emission spectrum had been…
Search for LBVs in the Local Volume galaxies: study of four stars in NGC 4449
Y. Solovyeva, A. Vinokurov, A. Sarkisyan +8
We continue to search for LBV stars in galaxies outside the Local Group. In this work, we have investigated four luminous stars in NGC 4449. Multiple spectral observations carried…
Modeling spectra of MN112
A. Kostenkov, S. Fabrika, O. Sholukhova +2
MN112 is the Galactic luminous blue variable (LBV) candidate with circumstellar nebula. P Cygni is the first discovered LBV, which was recorded during major eruptions in the 17th c…
Luminous Blue Variable candidates in M31
A. Sarkisyan, O. Sholukhova, S. Fabrika +7
We study five Luminous Blue Variable (LBV) candidates in the Andromeda galaxy and one more (MN112) in the Milky Way. We obtain the same-epoch near-infrared (NIR) and optical spectr…
Chemical Abundances in a Sample of Red Giants in the Open Cluster NGC 2420 from APOGEE
Diogo Souto, Katia Cunha, Verne Smith +20
NGC 2420 is a 2 Gyr-old well-populated open cluster that lies about 2 kpc beyond the solar circle, in the general direction of the Galactic anti-center. Most previous abundan…
