Context: .Statistical properties of H ii region populations in disk galaxies yield important clues to the physics of massive star formation. Aims: .We present a...

Stars and planets both form by accreting material from a surrounding disk. Because they grow from the same material, theory predicts that there should be a...

In recent years, science simulations have become popular among educators due to their educational usefulness, availability, and potential for increasing the...

We produce and analyse eclipse time variation (ETV) curves for some 2600 Kepler binaries. We find good to excellent evidence for a third body in 222 systems via...

We report the results we derived analyzing photometric measurements obtained at different phase angles for 15 Near-Earth Objects (NEOs), observed from Campo...

We present high-resolution maps of stars, dust, and molecular gas in a strongly lensed submillimeter galaxy (SMG) at z = 3.259. HATLAS J114637.9-001132 is...

We present results from a photometric Hα survey of 22 nuclear rings, aiming to provide insight into their star formation properties, including age distribution...

Chemical analyses of late-type stars are usually carried out following the classical recipe: LTE line formation and homogeneous, plane-parallel, flux-constant...

New calculations of the Galactic contamination over microwave background radiation anisotropies are carried out. On the one hand, when a frequency-dependent...
