HD 7977 and its possible influence on Solar System bodies
Piotr A. Dybczyński, Małgorzata Królikowska, Przemysław Bartczak +5
In the latest Gaia third data release one can find extremely small proper motion components for the star HD 7977. This, together with the radial velocity measurement lead to the co…
Properties of slowly rotating asteroids from the Convex Inversion Thermophysical Model
A. Marciniak, J. Ďurech, V. Alí-Lagoa +73
Results from the TESS mission showed that previous studies strngly underestimated the number of slow rotators, revealing the importance of studying those asteroids. For most slowly…
GN-z11-flash was a signal from a man-made satellite not a gamma-ray burst at redshift 11
Michał J. Michałowski, Krzysztof Kamiński, Monika K. Kamińska +1
Long gamma-ray bursts (GRB), explosions of very massive stars, provide crucial information on stellar and galaxy evolution, even at redshifts z ~ 8 - 9.5, when the Universe was onl…
Thermal properties of slowly rotating asteroids: Results from a targeted survey
A. Marciniak, V. Alí-Lagoa, T. G. Müller +51
Context. Earlier work suggests that slowly rotating asteroids should have higher thermal inertias than faster rotators because the heat wave penetrates deeper into the sub-surface.…
Photometric and spectroscopic variability of 53 Per
E. Niemczura, A. Pigulski, H. Lehmann +4
A new investigation of the variability of the SPB-type star 53 Per is presented. The analysis of the BRITE photometry allowed us to determine eight independent frequencies and the…
Against the biases in spins and shapes of asteroids
A. Marciniak, F. Pilcher, D. Oszkiewicz +21
Physical studies of asteroids depend on an availability of lightcurve data. Targets that are easy to observe and analyse naturally have more data available, so their synodic period…
Photometric survey, modelling, and scaling of long-period and low-amplitude asteroids
A. Marciniak, P. Bartczak, T. Müller +40
The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes. As a consequence of these select…
Shape and spin determination of Barbarian asteroids
M. Devogèle, P. Tanga, P. Bendjoya +51
Context. The so-called Barbarian asteroids share peculiar, but common polarimetric properties, probably related to both their shape and composition. They are named after (234) Barb…
ESpeRo: Echelle Spectrograph Rozhen
Tanyu Bonev, Haralambi Markov, Toma Tomov +11
In this paper we describe the echelle spectrograph of the 2 meter telescope of the Rozhen National Astronomical Observatory. The spectrograph is a cross-dispersed, bench-mounted, f…
CCD photometry of bright stars using objective wire mesh
Krzysztof Kamiński, Aleksander Schwarzenberg-Czerny, Marika Zgórz
Obtaining accurate photometry of bright stars from the ground remains tricky because of the danger of overexposure of the target and/or lack of suitable nearby comparison star. The…
mu Eridani from MOST and from the ground: an orbit, the SPB component's fundamental parameters, and the SPB frequencies
M. Jerzykiewicz, H. Lehmann, E. Niemczura +15
MOST time-series photometry of mu Eri, an SB1 eclipsing binary with a rapidly-rotating SPB primary, is reported and analyzed. The analysis yields a number of sinusoidal terms, main…
Asteroids' physical models from combined dense and sparse photometry and scaling of the YORP effect by the observed obliquity distribution
J. Hanuš, J. Ďurech, M. Brož +116
The larger number of models of asteroid shapes and their rotational states derived by the lightcurve inversion give us better insight into both the nature of individual objects and…
