ABSTRACT: The presence of liquid water has been hypothesized as an important ingredient for planet habitability. A sub-Neptune mass planet with a liquid water ocean below a hydrogen-rich envelope is an intriguing prospect. If the planet transits...

ABSTRACT: The galaxy population appears to be composed of infinitely complex different types and properties at first sight. However, when large samples of galaxies are studied, it appears that the vast majority of galaxies just follow simple scaling...

ABSTRACT: Magnetohydrodynamic (MHD) turbulence driven by the magnetorotational instability (MRI) has long been considered as the most promising mechanism for transporting angular momentum in accretion disks. In protoplanetary disks (PPDs), however...

ABSTRACT: We consider the Roche accretion in an Extreme Mass-Ratio Inspiral (EMRI) binary system formed by a star orbiting a massive black hole. The ultimate goal is to constrain the mass and spin of the black hole and confirm general relativity...

ABSTRACT: Recent surveys have established increasingly precise correlations between star formation rates (SFRs) and the gas, stellar, and dark matter contents of galaxies. Outer galactic disks are dominated by atomic gas and have steep Kennicutt...
