In addition to the large-scale outflows, which form their round, elliptical, and bipolar shells, planetary nebulae (PNe) also have, usually on smaller scales...

Given observed equivalent widths of Mg II and Mg I absorptions due to an interstellar cloud in which a late-B star is embedded, it is shown that the basic...

NSVS 10653195 is a double-line detached eclipsing binary star found in 2007 by te{coughlin2007} among the NSVS periodic variable stars. The first analysis of...

The aim of this study is to determine the physical parameters of the binary V1430 Aql from the study of light curves obtained in different filters V, R, I, J...

The near-Earth object (NEO) population is composed of asteroids and comets that have orbits close to the Earth. This vicinity to the Earth gives us some...

Convex shape models and spin vectors of asteroids are now routinely derived from their disk-integrated lightcurves by the lightcurve inversion method of...

Astrometric observations of binary brown dwarfs yield dynamical masses of the components independently of theoretical models. We give an update on our long-term...

In this work we analyze the star formation rates and stellar masses of a sample of 157 star forming galaxies at z ˜ 0.84 (Villar et al. 2008), selected by their...

Two very bright stellar occultations by Hi'iaka, the largest satellite of the dwarf planet Haumea, were predicted to take place during in April 2021. Since the...
