Time-dependent modelling of short-term variability in the TeV-blazar VER J0521+211 during the major flare in 2020
MAGIC Collaboration, S. Abe, J. Abhir +228
The BL Lacertae object VER J0521+211 underwent a notable flaring episode in February 2020. A short-term monitoring campaign, led by the MAGIC (Major Atmospheric Gamma Imaging Chere…
Investigation of the Nature of the B[e] Star CI Cam in the Optical Range
E. A. Barsukova, A. N. Burenkov, V. P. Goranskij +10
We report the results of 24 years of photometric and spectroscopic monitoring of CI Cam since its outburst in 1998. In the early years of our research, we identified a system compo…
The possible dual nature of the asteroid (12499) 1998 FR47
G. Borisov, N. Todorovic, E. Vchkova-Bebekovska +2
We present the R-band lightcurves of the Flora family asteroid (12499) 1998 FR47, obtained in 2022 at two different astronomical sites: Bulgarian National Astronomical Observatory…
Radio-loudness statistics of quasars from Quaia-VLASS
Nestor Arsenov, Sandor Frey, András Kovács +1
Quasars are objects of high interest in extragalactic astrophysics, cosmology, and astrometry. One of their useful qualities is their potential radio loudness. However, the fractio…
A wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour
C. M. Raiteri, M. Villata, M. I. Carnerero +96
Blazars are beamed active galactic nuclei known for their strong multi-wavelength variability on timescales from years down to minutes. We aim to investigate the suitability of the…
4D Grid-fitting of UV-optical spectra of massive stars. I. Numerical technique and its associated uncertainties
Blagovest V. Petrov, Svetozar A. Zhekov
The best way to check the validity of our theories (models) is by direct comparison with the experiment (observations). In this study, we address the numerical inaccuracies intrins…
S-Process Nucleosynthesis in Chemically Peculiar Binaries
A. J. Dimoff, C. J. Hansen, R. J. Stancliffe +4
Around half of the heavy elements in the universe are formed through the slow neutron capture (s-) process, which takes place in thermally pulsing asymptotic giant branch (AGB) sta…
Coma composition and profiles of comet 12P/Pons-Brooks using long-slit spectroscopy
Lea Ferellec, Cyrielle Opitom, Abbie Donaldson +4
Comet 12P/Pons-Brook exhibited multiple large and minor outbursts in 2023 on its way to its 2024 perihelion, as it has done during its previous apparitions. We obtained long-slit o…
Predictions for Sparse Photometry of Jupiter-Family Comet Nuclei in the LSST Era
A. Donaldson, C. Snodgrass, R. Kokotanekova +1
The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory will deliver high-quality, temporally-sparse observations of millions of Solar System objects on an unpreced…
A new dimension in the variability of AGB stars: convection patterns size changes with pulsation
A. Rosales-Guzmán, J. Sanchez-Bermudez, C. Paladini +16
Stellar convection plays an important role in atmospheric dynamics, wind formation and the mass-loss processes in Asymptotic Giant Branch (AGB) stars. However, a direct characteriz…
Optical variability of the blazar 3C 371: from minute to year timescales
J. Otero-Santos, C. M. Raiteri, J. A. Acosta-Pulido +41
The BL Lac object 3C 371 has been observed by the Transiting Exoplanet Survey Satellite (\textit{TESS}) for approximately a year, between July 2019 and July 2020, with an unmatched…
Tracking the motion of a shock along a channel in the low solar corona
J. Rigney, P. T. Gallagher, G. Ramsay +4
Shock waves are excited by coronal mass ejections (CMEs) and large-scale extreme-ultraviolet (EUV) wave fronts and can result in low-frequency radio emission under certain coronal…
Latest Evolution of the X-Ray Remnant of SN 1987A: Beyond the Inner Ring
Aravind P. Ravi, Sangwook Park, Svetozar A. Zhekov +5
Based on our Chandra imaging-spectroscopic observations, we present the latest evolution of the X-ray remnant of SN 1987A. Recent changes in the electron temperatures and volume em…
Proper motion of Cygnus loop shock filaments
M. Vucetic, N. Milanovic, D. Urosevis +4
We determined shock speed in the Galactic supernova remnant Cygnus Loop, using proper motion of its optical filaments and the latest estimate for its distance. The proper motion wa…
The variability patterns of the TeV blazar PG 1553+113 from a decade of MAGIC and multi-band observations
MAGIC Collaboration, H. Abe, S. Abe +264
PG 1553+113 is one of the few blazars with a convincing quasi-periodic emission in the gamma-ray band. The source is also a very high-energy (VHE; >100 GeV) gamma-ray emitter. To b…
