Refined reduction and standardisation of 53 years of UBV photometry at Hvar

Hrvoje Božić, Petr Harmanec, Miroslav Brož +17

Emission-line stars classified as Be exhibit light and colour variability on various timescales, ranging from days to decades. Their evolution must be constrained by long-term obse…

The first hours and days of the 2021 explosion of the recurrent symbiotic nova RS Ophiuchii

Augustin Skopal, Martin Vrašťák, Francois Teyssier +4

The accretion of matter on a massive white dwarf (WD) can lead to repeated nuclear explosions on its surface over a timescale of years to decades. The seventh explosion of the recu…

Photometric study of fourteen low-mass binaries

David Korda, Petr Zasche, Marek Wolf +3

New CCD photometric observations of fourteen short-period low-mass eclipsing binaries (LMB) in the photometric filters I, R and V were used for the light curve analysis. There stil…

New outburst of the symbiotic nova AG Peg after 165 years

A. Skopal, S. Yu. Shugarov, M. Sekeráš +13

AG Peg is known as the slowest symbiotic nova, which experienced its nova-like outburst around 1850. After 165 years, during June of 2015, it erupted again showing characteristics…

V773 Cas, QS Aql, and BR Ind: Eclipsing Binaries as Parts of Multiple Systems

P. Zasche, J. Jurysek, J. A. Nemravova +9

Eclipsing binaries remain crucial objects for our understanding of the universe. In particular, those that are components of multiple systems can help us solve the problem of the f…

The orbital elements and physical properties of the eclipsing binary BD+36 3317, a probable member of Lyr cluster

E. Kıran, P. Harmanec, Ö. L. Değirmenci +4

Context. The fact that eclipsing binaries belong to a stellar group is useful, because the former can be used to estimate distance and additional properties of the latter, and vice…
