A global view on the colliding-wind binary WR 147
Svetozar A. Zhekov, Blagovest V. Petrov, Toma V. Tomov +1
We present results from a global view on the colliding-wind binary WR 147. We analysed new optical spectra of WR 147 obtained with Gran Telescopio CANARIAS and archive spectra from…
AT 2019abn: multi-wavelength observations over the first 200 days
S. C. Williams, D. Jones, P. Pessev +8
AT 2019abn was discovered in the nearby M51 galaxy by the Zwicky Transient Facility at more than two magnitudes and around three weeks prior to its optical peak. We aim to conduct…
Independent Study and Spectral Classification of a Sample of Poorly Studied High Proper Motion M-dwarf Candidate Stars
Cristina Cabello, Géza Csörnyei, Jaroslav Merc +2
We report an independent spectral classification of a sample of poorly studied M-dwarf candidate stars observed with the OSIRIS instrument at GTC. Our project was carried out as an…
The January 2015 outburst of a red nova in M31
Alexander Kurtenkov, Peter Pessev, Toma Tomov +19
M31N 2015-01a (or M31LRN 2015) is a red nova that erupted in January 2015 -- the first event of this kind observed in M31 since 1988. Very few similar events have been confirmed as…
The Brightening of Re50N: Accretion Event or Dust Clearing?
Hsin-Fang Chiang, Bo Reipurth, Josh Walawender +5
The luminous Class I protostar HBC 494, embedded in the Orion A cloud, is associated with a pair of reflection nebulae, Re50 and Re50N, which appeared sometime between 1955 and 197…
Chemical Abundances of the Highly Obscured Galactic Globular Clusters 2MASS GC02 and Mercer 5
Francisco Penaloza, Peter Pessev, Sergio Vasquez +3
We present the first high spectral resolution abundance analysis of two newly discovered Galactic globular clusters, namely Mercer 5 and 2MASS GC02 residing in regions of high inte…
