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…

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…

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…
