Highly bipolar planetary nebula Hen 2-57 and its possible symbiotic core

J. Merc, J. Mikołajewska, K. Iłkiewicz +1

We present a multi-wavelength analysis of the highly bipolar object Hen 2-57 based on new optical spectroscopy from the Southern African Large Telescope (SALT), complemented by arc…

Identification of new Galactic symbiotic stars with SALT -- II. New discoveries and characterization of the sample

J. Merc, J. Mikołajewska, K. Iłkiewicz +2

We present the continuation of a systematic search for new southern Galactic symbiotic stars, selecting candidates from the SuperCOSMOS H Survey and 2MASS. Follow-up spectroscop…

Blending-induced beating and emission in the symbiotic star Terz V 2513

J. Merc, J. Mikołajewska, C. Gałan +4

We present a detailed analysis of Terz V 2513 (=2MASS J17334728-2719266), a poorly studied symbiotic star. Our motivation was a peculiar beating pattern in its light curves from al…

A 70 pc-Diameter Nova Super-remnant Surrounding the Recurrent Nova RS Ophiuchi

Michael M. Shara, Kenneth M. Lanzetta, Alexandra Masegian +9

Recurrent novae undergo thermonuclear-powered eruptions separated by less than 100 years, enabled by subgiant or red giant donors transferring hydrogen-rich matter at very high rat…

The Newly Discovered Nova Super-Remnant Surrounding Recurrent Nova T Coronae Borealis: Will it Light Up During the Coming Eruption?

Michael M. Shara, Kenneth M. Lanzetta, Alexandra Masegian +7

A century or less separates the thermonuclear-powered eruptions of recurrent novae in the hydrogen-rich envelopes of massive white dwarfs. The colliding ejecta of successive recurr…

Ancient nova shells of RX Pup indicate evolution of mass transfer rate

Krystian Ilkiewicz, Joanna Mikolajewska, Michael M. Shara +1

RX Pup is a symbiotic binary which experienced a nova outburst in the 1970's. Here we report a discovery of a ~1300 year old nova shell around the system and a possible detection o…
