Photometry and spectroscopy of the new symbiotic star 2SXPS J173508.4-292958
U. Munari, P. Valisa, A. Vagnozzi +3
We present and discuss the results of our photometric and spectroscopic monitoring of 2SXPS J173508.4-292958 carried out from April to August 2020. This X-ray source, in the foregr…
AR Ser: photometric observations of a Blazhko star
Michel Bonnardeau, Franz-Josef Hambsch
Photometric observations in 2010-2014 of the RR Lyrae star AR Serpentis are presented and analyzed. Two Blazhko modulations of comparable amplitude are detected, with the periods 8…
An Asymmetric Eclipse Seen Towards the Pre-Main Sequence Binary System V928 Tau
Dirk van Dam, Matthew Kenworthy, Trevor David +21
K2 observations of the weak-lined T Tauri binary V928 Tau A+B show the detection of a single, asymmetric eclipse which may be due to a previously unknown substellar companion eclip…
Fermi-LAT Observations of V549 Vel 2017: a Sub-Luminous Gamma-Ray Nova?
Kwan-Lok Li, Franz-Josef Hambsch, Ulisse Munari +4
We report on the Fermi-LAT detection (with ~5.7 sigma significance) as well as the multi-wavelength analysis of the 2017 nova eruption V549 Vel. Unlike the recent shock-powered nov…
High-Amplitude gamma Doradus Variables
Ernst Paunzen, Klaus Bernhard, Stefan Huemmerich +3
According to most literature sources, the amplitude of the pulsational variability observed in gamma Doradus stars does not exceed 0.1 mag in Johnson V. We have analyzed fifteen hi…
IM Normae: The Death Spiral of a Cataclysmic Variable?
Joseph Patterson, Jonathan Kemp, Berto Monard +18
We present a study of the orbital light curves of the recurrent nova IM Normae since its 2002 outburst. The broad "eclipses" recur with a 2.46 hour period, which increases on a tim…
