Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects
The Astrophysical JournalSmall planets (≲1 M _⊕ ) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and ...

TASK Quarterly, 2019 The matrix Green’s function of the initial-boundary value problem of admixture double-diffusivity is defined. The initial-boundary value problem with a point source is formulated for the matrix elements for determination of the matrix Green’s function ...

Constraining the Thin Disc Initial Mass Function using Galactic Classical Cepheids [PDF]
, 2016 Context: The Initial Mass Function (IMF) plays a crucial role on galaxy evolution and its implications on star formation theory make it a milestone for the next decade. It is in the intermediate and high mass ranges where the uncertainties of the IMF are

The Origin and Universality of the Stellar Initial Mass Function
, 2014 We review current theories for the origin of the Stellar Initial Mass Function (IMF) with particular focus on the extent to which the IMF can be considered universal across various environments.

Do Red Galaxies Form More Stars than Blue Galaxies?
The Astrophysical JournalA new model is proposed in which typical galaxies form most of their stellar mass in a phase with an intrinsically red stellar population. In the standard picture, galaxies with intrinsically red stellar populations are believed to have old stellar ...

The Formation of Low-Mass Cluster Galaxies and the Universal Initial Galaxy Mass Function
, 2002 Clusters of galaxies have an observed over-density of low-luminosity systems in comparison to the field, although it is not yet agreed whether this effect is the result of initial galaxy mass functions that vary with environment or galaxy evolutionary ...

ON THE ORIGIN OF THE SALPETER SLOPE FOR THE INITIAL MASS FUNCTION [PDF]
The Astrophysical Journal, 2011 We suggest that the intrinsic, stellar initial mass function (IMF) follows a power-law slope gamma=2, inherited from hierarchical fragmentation of molecular clouds into clumps and clumps into stars. The well-known, logarithmic Salpeter slope GAMMA=1.35 in clusters is then the aggregate slope for all the star-forming clumps contributing to an individual
