Context. Hot Jupiters (HJs) with close-by planetary companions are rare, with only a handful of them having been discovered so far. This could be due to their...

We present a method for speckle holography that is optimized for crowded fields. Its two key features are an iterative improvement of the instantaneous point...

Context. The solar magnetic field is responsible for all aspects of solar activity. Thus, emergence of magnetic flux at the surface is the first manifestation...

We report on the high-resolution spectroscopic observations of two planetary transits of the hot Jupiter KELT-7b (M p = 1.28 ± 0.17M Jup, T eq = 2028 K)...

Ultra-hot Jupiters offer interesting prospects for expanding our theories on dynamical evolution and the properties of extremely irradiated atmospheres. In this...

We study the density profiles of collapsed galaxy-size dark matter halos with masses 1011 to 5×1012 Msolar focusing mostly on the halo outer regions from the...

An optimal window for image analysis is determined by means of information theory. The size of the window is then used as a good estimator of image quality. The...

Context. Anti-solar differential rotation profiles have been found for decades in numerical simulations of convective envelopes of solar-type stars. These...

IAC-pop is a code designed to solve the star formation history (SFH) of a complex stellar population system, like a galaxy, from the analysis of the color...
