In this paper, we present a thorough study of the T Tauri system MO Lup. We report on its previously unrecognized triple spectroscopic nature. Our study is...

Only by incorporating various forms of feedback can theories of galaxy formation reproduce the present-day luminosity function of galaxies. It has also been...

A comparison between linear-stability analysis and observations of pulsation modes in five δ Scuti stars, belonging to the same cluster, is presented. The study...

The software package CAOS (code for adaptive optics systems) described in this paper is a software ensemble of modules designed for end-to-end simulation of...

We present V-band surface photometry and major-axis kinematics of stars and ionized gas of three early-type spiral galaxies, namely NGC 772, 3898 and 7782. For...

The characterization of the atomic and molecular hydrogen content of high-redshift galaxies is a major observational challenge that will be addressed over the...

Type Ia Supernovae (SNe Ia) are a critical tool in measuring the accelerating expansion of the universe. Recent efforts to improve these standard candles have...

We present an analysis of optical and infrared spectra of the recurrent nova RS Oph obtained during between 2006 and 2009. The best fit to the optical spectrum...

CO observations allow estimation of the gas content of molecular clouds, which trace the reservoir of cold gas fuelling star formation, as well as determination...
