Revisiting BV & BW Draconis: Detailed Study of Intriguing Multiple System
J. J. Tokarek, W. Dimitrov, M. Polińska +6
The BV & BW Draconis system is a unique coplanar system of two eclipsing contact binaries. The main objective of this study is to develop a model based on new observations. The onl…
Asteroid sizes determined with thermophysical model and stellar occultations
A. Choukroun, A. Marciniak, J. Ďurech +165
Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…
HI and CO spectroscopy of the unusual host of GRB 171205A: A grand design spiral galaxy with a distorted HI field
A. de Ugarte Postigo, M. Michalowski, C. C. Thoene +22
GRBs produced by the collapse of massive stars are usually found near the most prominent star-forming regions of star-forming galaxies. GRB 171205A happened in the outskirts of a s…
The interstellar medium in the environment of the supernova-less long-duration GRB 111005A
Aleksandra Leśniewska, M. J. Michałowski, P. Kamphuis +17
Long ( s) gamma ray bursts (GRBs) are associated with explosions of massive stars, although in three instances, supernovae (SNe) have not been detected, despite deep observatio…
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.…
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…
Spectroscopic survey of Kepler stars. II. FIES/NOT observations of A- and F-type stars
E. Niemczura, M. Polińska, S. J. Murphy +7
We have analysed high-resolution spectra of 28 A and 22 F stars in the Kepler field, observed with the FIES spectrograph at the Nordic Optical Telescope. We provide spectral types,…
High-resolution spectroscopy and abundance analysis of Delta Scuti stars near the Gamma Doradus instability strip
F. Kahraman Aliçavuş, E. Niemczura, M. Polińska +5
Scuti stars are remarkable objects for asteroseismology. In spite of decades of investigations, there are still important questions about these pulsating stars to be answered,…
Interplay between pulsations and mass loss in the blue supergiant 55 Cygnus = HD 198478
M. Kraus, M. Haucke, L. S. Cidale +14
Blue supergiant stars are known to display photometric and spectroscopic variability that is suggested to be linked to stellar pulsations. Pulsational activity in massive stars str…
The non-convex shape of (234) Barbara, the first Barbarian
P. Tanga, B. Carry, F. Colas +37
Asteroid (234) Barbara is the prototype of a category of asteroids that has been shown to be extremely rich in refractory inclusions, the oldest material ever found in the Solar Sy…
Physical properties of ESA Rosetta target asteroid (21) Lutetia: Shape and flyby geometry
B. Carry, M. Kaasalainen, C. Leyrat +22
Aims. We determine the physical properties (spin state and shape) of asteroid (21) Lutetia, target of the ESA Rosetta mission, to help in preparing for observations during the flyb…
New determination of the size and bulk density of the binary asteroid 22 Kalliope from observations of mutual eclipses
P. Descamps, F. Marchis, J. Pollock +16
In 2007, the M-type binary asteroid 22 Kalliope reached one of its annual equinoxes. As a consequence, the orbit plane of its small moon, Linus, was aligned closely to the Sun's li…
