Substellar Objects in Nearby Young Clusters (SONYC) II: The Brown Dwarf Population of Rho Ophiuchi
Substellar Objects Nearby Young Clusters
2011/1/11
SONYC - Substellar Objects in Nearby Young Clusters - is a survey program to investigate the frequency and properties of brown dwarfs down to masses below the Deuterium burning limit in nearby star fo...
Stellar and substellar mass function of the young open cluster candidates Alessi 5 and beta Monocerotis
Stellar substellar mass young open cluster candidates beta Monocerotis
2010/11/10
Although the stellar and substellar populations have been studied in various young and old open clusters, additional studies in clusters in the age range from 5 to 100Myr is crucial (e.g. to give more...
Connections Between Tilted Accretion Disks Around White Dwarfs and Substellar Companions
Substellar companions infrared excess debris disks protoplanetary disks exo-zodiacal dust
2010/11/16
Accretion disks in white dwarf systems are believed to be tilted. In a recent publication, the lift force has been suggested to be a source to disk tilt, a source that is likely relevant to all accret...
Stellar and substellar initial mass function: a model that implements gravoturbulent fragmentation and accretion
Solar and Stellar Astrophysics (astro-ph.SR) Galaxy Astrophysics (astro-ph.GA)
2010/12/28
In this work, we derive the stellar initial mass function (IMF) from the superposition of mass distributions of dense cores, generated through gravoturbulent fragmentation of unstable clumps in molecu...
