BU Canis Minoris -- the Most Compact Known Flat Doubly Eclipsing Quadruple System
Theodor Pribulla, Tamás Borkovits, Rahul Jayaraman +25
We have found that the 2+2 quadruple star system BU CMi is currently the most compact quadruple system known, with an extremely short outer period of only 121 days. The previous re…
V907 Sco Switched to the Eclipsing Mode Again
P. Zasche, D. Vokrouhlický, B. N. Barlow +1
V907 Scorpii is a unique triple system in which the inner binary component has been reported to have switched on and off eclipses several times in modern history. In spite of its p…
GRB 190919B: Rapid optical rise explained as a flaring activity
Martin Jelínek, Martin Topinka, Sergey Karpov +17
Following the detection of a long GRB 190919B by INTEGRAL (INTErnational Gamma-Ray Astrophysics Laboratory), we obtained an optical photometric sequence of its optical counterpart.…
GRANDMA Observations of ZTF/Fink Transients during Summer 2021
V. Aivazyan, M. Almualla, S. Antier +80
We present our follow-up observations with GRANDMA of transient sources revealed by the Zwicky Transient Facility (ZTF). Over a period of six months, all ZTF triggers were examined…
The peculiar chemical pattern of the WASP-160 binary system: signatures of planetary formation and evolution?
Emiliano Jofré, Romina Petrucci, Yilen Gómez Maqueo Chew +8
Wide binary stars with similar components hosting planets provide a favorable opportunity for exploring the star-planet chemical connection. We perform a detailed characterization…
Exceptionally bright optical emission from a rare and distant ray burst
Gor Oganesyan, Sergey Karpov, Martin Jelínek +19
Long -ray bursts (GRBs) are produced by the dissipation of ultra-relativistic jets launched by newly-born black holes after the collapse of massive stars. Right after the lu…
TIC 454140642: A Compact, Coplanar, Quadruple-lined Quadruple Star System Consisting of Two Eclipsing Binaries
Veselin B. Kostov, Brian P. Powell, Guillermo Torres +30
We report the discovery of a compact, coplanar, quadruply-lined, eclipsing quadruple star system from TESS data, TIC 454140642, also known as TYC 0074-01254-1. The target was first…
TIC 168789840: A Sextuply-Eclipsing Sextuple Star System
Brian P. Powell, Veselin B. Kostov, Saul A. Rappaport +48
We report the discovery of a sextuply-eclipsing sextuple star system from TESS data, TIC 168789840, also known as TYC 7037-89-1, the first known sextuple system consisting of three…
The FRAM robotic telescope for atmospheric monitoring at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +377
FRAM (F/Photometric Robotic Atmospheric Monitor) is a robotic telescope operated at the Pierre Auger Observatory in Argentina for the purposes of atmospheric monitoring using stell…
A New Method for Aerosol Measurement using Wide-field Photometry
Jan Ebr, Sergey Karpov, Jiří Eliášek +11
We present a new method to measure the vertical aerosol optical depth (VAOD) during clear nights using a wide-field imager - a CCD camera with a photographic lens on an equatorial…
CzeV1731: The unique doubly eclipsing quadruple system
P. Zasche, Z. Henzl, H. Lehmann +14
We report the discovery of the relatively bright (V = 10.5 mag), doubly eclipsing 2+2 quadruple system CzeV1731. This is the third known system of its kind, in which the masses are…
GRANDMA Observations of Advanced LIGO's and Advanced Virgo's Third Observational Campaign
S. Antier, S. Agayeva, M. Almualla +55
GRANDMA is a network of 25 telescopes of different sizes, including both photometric and spectroscopic facilities. The network aims to coordinate follow-up observations of gravitat…
The first study of 54 new eccentric eclipsing binaries in our Galaxy
P. Zasche, M. Wolf, R. Uhlar +12
We present an analysis of the apsidal motion and light curve parameters of 54 never-before-studied galactic Algol-type binaries. This is the first analysis of such a large sample o…
The search for roAp stars: null results and new candidates from Stroemgren-Crawford photometry
E. Paunzen, G. Handler, K. Honkova +10
The rapidly oscillating Ap (roAp) stars exhibit pulsational photometric and/or radial velocity variations on time scales of several minutes, which are essential to test current pul…
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…
Bangs and Meteors from the Quiet Comet 15P/Finlay
Quan-Zhi Ye, Peter G. Brown, Charles Bell +3
Jupiter-family comet 15P/Finlay has been reportedly quiet in activity for over a century but has harbored two outbursts during its 2014/2015 perihelion passage. Here we present an…
