Context. The Hayabusa2 spacecraft launched by Japan Aerospace Exploration Agency has been conducting observations of the asteroid (162173) Ryugu since June 2018...

We test the modified Newtonian dynamics (MOND) theory with the velocity dispersion profiles of Galactic globular clusters populating the outermost region of the...

A significant fraction of an exoplanet transit model evaluation time is spent calculating projected distances between the planet and its host star. This is a...

The granulation pattern that we observe on the surface of the Sun is due to hot plasma rising to the photosphere where it cools down and descends back into the...

The motivation, techniques and performance of the ground-based photometric follow-up of transit detections by the CoRoT space mission are presented. Its...

Context. Lightning flashes in Jupiter have been observed by spacecraft orbiting the planet, but so far, they have escaped optical detection from Earth. However...

Recent observations have detected galaxies at high-redshift z∼ 6{--}11, and revealed the diversity of their physical properties, from normal star-forming...

Context: .Satellite accretion events have been invoked for mimicking the internal secular evolutionary processes of bulge growth. However, N-body simulations of...

Context. The potentially hazardous asteroid (PHA) (99942) Apophis is one of the most remarkable near-Earth asteroids (NEA) in terms of impact hazard. A good...
