V440 Per: the longest period overtone Cepheid
R. Baranowski, R. Smolec, W. Dimitrov +9
V440 Per is a Population I Cepheid with the period of 7.57 day and low amplitude, almost sinusoidal light and radial velocity curves. With no reliable data on the 1st harmonic, its…
Absolute properties of the main-sequence eclipsing binary FM Leo
M. Ratajczak, T. Kwiatkowski, A. Schwarzenberg-Czerny +9
First spectroscopic and new photometric observations of the eclipsing binary FM Leo are presented. The main aims were to determine orbital and stellar parameters of two components…
The XMM large scale structure survey: optical vs. X-ray classifications of active galactic nuclei and the unified scheme
O. Garcet, P. Gandhi, E. Gosset +25
Our goal is to characterize AGN populations by comparing their X-ray and optical classifications. We present a sample of 99 spectroscopically identified X-ray point sources in the…
Asteroids' physical models from combined dense and sparse photometry and scaling of the YORP effect by the observed obliquity distribution
J. HanuÅ¡, J. Äurech, 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…
