Gaia20fnr: A binary-lens microlensing event with full orbital motion revealed by four space telescopes
M. Wicker, Ł. Wyrzykowski, M. Hundertmark +49
The microlensing event Gaia20fnr is a long-duration, non-caustic-crossing binary-lens event at high Galactic latitude. Triggered by a photometric rise detected by the Gaia space mi…
Photometric Analysis of TCP J201712881156589 -- WZ Sge Type Dwarf Nova with Delayed Ordinary Superhumps Emergence
Alexander Tarasenkov, Sergey Shugarov, Natalia Ikonnikova +3
We present the results of photometric analysis of WZ Sge type dwarf nova TCP J201712881156589. This object exhibited an outburst with a large amplitude of magnitudes and…
The evolutionary history of ultra-compact accreting binaries. I. Chemical abundances and formation channel of the eclipsing AM CVn system ZTF J225237.05-051917.4 from HST spectroscopy
W. Yu, A. F. Pala, T. Kupfer +33
AM Canum Venaticorum (AM CVn) stars are ultra-compact binary systems composed of a white dwarf (WD) primary accreting from a H-deficient donor. They are important as potential prog…
Revisiting the extremely long-period cataclysmic variables V479 Andromedae and V1082 Sagitarii
Gagik Tovmassian, Diogo Belloni, Anna F. Pala +56
The overwhelming majority of CVs have orbital periods shorter than 10 hr. However, a few have much longer periods, and their formation and existence pose challenges for the CV evol…
TCP J072226836220548: a new AM CVn type system with infrequent outbursts
Alexander Tarasenkov, Kirill Sokolovsky, Alexandr Dodin +11
We present the discovery of TCP J072226836220548, a new ultracompact binary system of the AM CVn type. This system was first identified displaying a mag outburst on 2…
PM 1-322: new variable planetary nebula
E. Paunzen, K. Bernhard, J. Budaj +4
Spectra of planetary nebulae (PNe) are characterised by strong forbidden emission lines and often also by an infrared (IR) excess. A few PNe show dust obscuration events and/or har…
