A second terrestrial planet orbiting the nearby M dwarf LHS 1140
LHS 1140 is a nearby mid-M dwarf known to host a temperate rocky super-Earth (LHS 1140 b) on a 24.737-day orbit. Based on photometric observations by MEarth and...
A self-consistent procedure to detect low-l low-n solar p-modes
Recent data colleted by the helioseismic experiments aboard SOHO have allowed the detection of low degree p-modes with lower and lower order, n. In particular...
A Shift in Jupiter's Equatorial Haze Distribution Imaged with the Multi-Conjugate Adaptive Optics Demonstrator at the VLT
Jupiter was imaged during the Science Demonstration of the MCAO Demonstrator (MAD) at the European Southern Observatory's Very Large Telescope. Io and Europa...
A Shock Model for Quasars and Active Galactic Nuclei
First order Fermi acceleration is an efficient mechanism to produce relativistic particles in strong astrophysical shocks. The authors have developed a model...
A short-period sub-Earth orbiting Proxima Centauri
The discovery of a planetary candidate orbiting the habitable zone of our closest neighbor, Proxima Centauri (Gl 551), shook the planetary community as few...
A Shortcut to Calculate SPAM Limb-darkening Coefficients
We release a new grid of stellar limb-darkening coefficients (LDCs, using the quadratic, power-2 and claret-4 laws) and intensity profiles for the Kepler, U, B...
A simulated regolith medium for multi-wavelength studies
Effects arising from the small-scale surface structure are significant in remote studies of regolith surfaces on atmosphereless solar system bodies, such as the...
