Ten new, ultracompact triply eclipsing triple star systems
T. Borkovits, S. A. Rappaport, T. Mitnyan +15
We have identified more than a hundred close triply eclipsing hierarchical triple star systems from data taken with the space telescope TESS. Many of them have outer periods less t…
V4141 Sgr: Outflows and repeated outbursts
Jaroslav Merc, Joanna Mikołajewska, Thomas Petit +6
In this work, we analyze the ongoing brightening of the poorly studied symbiotic star V4141 Sgr and examine its long-term variability. We present new low-resolution spectroscopic o…
ASASSN-22ak: La Belle au bois dormant in a hydrogen-depleted dwarf nova?
Taichi Kato, Franz-Josef Hambsch, Berto Monard +1
ASASSN-22ak is a transient discovered by the All-Sky Automated Survey for Supernovae and by Gaia in 2022 January. Although this object had been in deep quiescence at least for seve…
Recurrent mini-outbursts and a magnetic white dwarf in the symbiotic system FN Sgr
J. Magdolen, A. Dobrotka, M. Orio +5
AIMS: We investigated the optical variability of the symbiotic binary FN Sgr, with photometric monitoring during 55 years and with a high-cadence Kepler light curve lasting…
Precision measurement of a brown dwarf mass in a binary system in the microlensing event OGLE-2019-BLG-0033/MOA-2019-BLG-035
A. Herald, A. Udalski, V. Bozza +89
Context. Brown dwarfs are poorly understood transition objects between stars and planets, with several competing mechanisms having been proposed for their formation. Mass measureme…
Investigating the low-flux states in six Intermediate Polars
Ava E. Covington, Aarran W. Shaw, Koji Mukai +30
We present optical photometry of six intermediate polars that exhibit transitions to a low-flux state. For four of these systems, DW Cnc, V515 And, V1223 Sgr and RX J2133.7+5107, w…
