Radiation-hydrodynamics of star-disc collisions: From system parameters to outflows and lightcurves
Taj Jankovič, Sergey Karpov, Michal Zajaček +2
Quasi-periodic eruptions (QPEs) are nuclear transients producing bright, repeating soft X-ray flares superimposed on quiescent emission. A promising interpretation is that they are…
Radiation-hydrodynamics of star-disc collisions for quasi-periodic eruptions
Taj Jankovič, Clément Bonnerot, Sergey Karpov +1
Quasi-periodic eruptions (QPEs) are recently discovered transients of unknown nature occurring near supermassive black holes, which feature bright X-ray bursts separated by hours t…
Lost and Found - A gallery of overlooked optical nuclear transients from the ZTF archive
E. Quintin, E. Russeil, M. Llamas Lanza +12
Tidal disruption events (TDEs) correspond to the destruction of a star by the tidal forces around a black hole, leading to outbursts which can last from months to years. These tran…
Contact binary asteroid (153201) 2000 WO107: rotation, shape model, and density
Yurij Krugly, Oleksiy Golubov, Ihor Kyrylenko +10
We combine different methods to investigate the rotation, determine the shape and estimate the density of near-Earth asteroid (153201) 2000 WO. We carried out photometric o…
Early Identification of Optical Tidal Disruption Events: A science module for the Fink broker
Miguel Llamas Lanza, Sergey Karpov, Etienne Russeil +5
The detection of tidal disruption events (TDEs) is one of the key science goals of large optical time-domain surveys such as the Zwicky Transient Facility (ZTF) and the upcoming Ve…
Aerosol Measurement in B, V, and R Filters using Wide-field Photometry
Shefali Negi, Jan Ebr, Sergey Karpov +1
The new method for aerosol measurement using wide-field stellar photometry was originally developed for B-filter data. The dependence of VAOD (vertical aerosol optical depth) on wa…
Limits on the Ejecta Mass During the Search for Kilonovae Associated with Neutron Star-Black Hole Mergers: A case study of S230518h, GW230529, S230627c and the Low-Significance Candidate S240422ed
M. Pillas, S. Antier, K. Ackley +78
Neutron star-black hole (NSBH) mergers, detectable via their gravitational-wave (GW) emission, are expected to produce kilonovae (KNe). Four NSBH candidates have been identified an…
STDWeb: Simple Transient Detection pipeline for the Web
Sergey Karpov
We present a simple web-based tool, STDWeb, for a quick-look photometry and transient detection in astronomical images. It tries to implement a self-consistent and mostly automatic…
New ultracool dwarf candidates from multi-epoch WISE data
Sergey Karpov, Oleg Malkov, Aleksandra Avdeeva
Thirty years after the discovery of brown dwarfs, the search for these objects continues, particularly in the vicinity of the Sun. Objects near the Sun are characterized by large p…
The rate of satellite glints in ZTF and LSST sky surveys
Sergey Karpov, Julien Peloton
We assess the impact of satellite glints -- rapid flashes produced by reflections of a sunlight from flat surfaces of rotating satellites -- on current and future deep sky surveys…
Ready for O4 II: GRANDMA Observations of Swift GRBs during eight-weeks of Spring 2022
I. Tosta e Melo, J. -G. Ducoin, Z. Vidadi +106
We present a campaign designed to train the GRANDMA network and its infrastructure to follow up on transient alerts and detect their early afterglows. In preparation for O4 II camp…
