First X-ray detection of symbiotic nova CN Cha with eROSITA/SRG

Sara Saeedi, Jaroslav Merc, Manami Sasaki +2

Aims. We report on the first X-ray detection of the symbiotic star CN Cha with eROSITA (extended Roentgen Survey with an Imaging Telescope Array) onboard Spektrum-Roentgen Gamma (S…

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…

K 1-6 is a photoionised ISM nebula shaped by a fast-moving hot white dwarf in a triple system

Jaroslav Merc, David Jones, Ana Escorza +22

K 1-6 has long been classified as a planetary nebula (PN) hosting a binary central star, yet it has remained poorly studied due to its faintness. The central star exhibits pronounc…

Symbiotic binaries in the Gaia data. II. Symbiotic candidates from general variability classification in DR3

Jaroslav Merc, Lionel Mulato, Joanna Mikołajewska +7

We investigate the reliability of the symbiotic star class in the general variability classification of Gaia DR3 and search for new genuine symbiotic systems among the objects assi…

Symbiotic binaries in the Gaia data. I. Known symbiotics in DR3 and FPR

Jaroslav Merc

Symbiotic stars are long-period interacting binaries composed of an evolved giant and a hot compact companion. Their complex spectra and variability make them both astrophysically…

Analysis of the Gaia DR3 planetary nebula candidates and the possible symbiotic stars among them

Lionel Mulato, Jaroslav Merc, Stéphane Charbonnel +3

The Gaia DR3, released in June 2022, included low-resolution BP/RP (XP) spectra that have been exploited for the classification of various types of emission-line objects using mach…
