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

Jaroslav Merc, David Jones, Ana Escorza, Henri M. J. Boffin et autres

K 1-6 has long been classified as a planetary nebula (PN) hosting a binary central star; however, it has remained poorly studied due to its faintness. The central star exhibits pronounced photometric variability whose origin is still unclear. We present a comprehensive …

New Online Database of Symbiotic Variables: Catalog and Statistical Overview of Symbiotic Binaries

Jaroslav Merc, R. Gális, M. Wolf

Abstract We present the New Online Database of Symbiotic Variables (NODSV), a comprehensive and publicly accessible catalog of known and candidate symbiotic stars in the Milky Way and nearby galaxies. The database provides an up-to-date census of confirmed symbiotic binaries and systematically …

TESS light curves and surface activity in two low-mass eclipsing binaries: NSVS 01031772 and 2MASS J04100497+2931023

M. Wolf, L. Šmelcer, H. Kučáková, A. Oplištilová et autres

The VRIC light curves were regularly measured for two eclipsing binaries, NSVS 01031772 and 2MASS J04100497+2931023 as part of our long-term observational project to study low-mass eclipsing binaries with a short orbital period and surface activity. The solution of the Tess light …

Apsidal motion and TESS light curves of two southern eclipsing binaries with high eccentricity: V1647 Sgr and V2283 Sgr

M. Wolf, P. Zasche, Miloslav Zejda, M. Mašek

The study of apsidal motion rates in eccentric eclipsing binaries provides an important observational test of theoretical models of stellar structure and evolution. Precise physical parameters of the stellar components together with systematic measurements of the periastron advance are needed. We present …
