Galactic stellar and substellar initial mass function
We review recent determinations of the present-day mass function (PDMF) and initial mass function (IMF) in various components of the Galaxy—disk, spheroid, young, and globular clusters—and inExpand
Evolutionary models for cool brown dwarfs and extrasolar giant planets. The case of HD 209458
We present evolutionary models for cool brown dwarfs and extra-solar giant planets. The models re- produce the main trends of observed methane dwarfs in near-IR color-magnitude diagrams. We alsoExpand
Evolutionary Models for Very Low-Mass Stars and Brown Dwarfs with Dusty Atmospheres
We present evolutionary calculations for very low-mass stars and brown dwarfs based on synthetic spectra and nongray atmosphere models which include dust formation and opacity, i.e., objects withExpand
New evolutionary models for pre-main sequence and main sequence low-mass stars down to the hydrogen-burning limit
We present new models for low-mass stars down to the hydrogen-burning limit that consistently couple atmosphere and interior structures, thereby superseding the widely used BCAH98 models. The newExpand
The Galactic Disk Mass Function: Reconciliation of the Hubble Space Telescope and Nearby Determinations
We derive and parameterize the Galactic mass function (MF) below 1 M☉ characteristic of both single objects and binary systems. We resolve the long-standing discrepancy between the MFs derived fromExpand
The Galactic Disk Mass Budget. I. Stellar Mass Function and Density
In this paper, we use the general theory worked out within the past few years for the structure and the evolution of low-mass stars to derive the stellar mass function in the Galactic disk down toExpand
Evolutionary models for low-mass stars and brown dwarfs: uncertainties and limits at very young ages
We analyse pre-Main Sequence evolutionary tracks for low mass stars with masses $m \\le 1.4 \\msol$ based on the Baraffe et al. (1998) input physics. We also extend the recent Chabrier et al. (2000)Expand
The Initial Mass Function: From Salpeter 1955 to 2005
Fifty years after Ed Salpeter's seminal paper, tremendous progress both on the observational and theoretical sides allow a fairly accurate determination of the Galactic IMF not only down to theExpand
Theory of Low-Mass Stars and Substellar Objects
▪ Abstract Since the discovery of the first bona-fide brown dwarfs and extra-solar planets in 1995, the field of low-mass stars and substellar objects has progressed considerably, both from theoret...
