Formation of massive stars by growing accretion rate
We perform calculations of pre-main sequence evolution of stars from 1 to 85M⊙ with growing accretion rates Ṁ . The values of Ṁ are taken equal to a constant fraction f̃ of the rates of the mass outflows observed by Churchwell (1998) and Henning (2000). The evolution of the various stellar parameters is given, as well as the evolution of the disc luminosity; electronic tables are provided as a s...
متن کاملInfall of planetesimals onto growing giant planets: onset of runaway gas accretion and metallicity of their gas envelopes
We have investigated the planetesimal accretion rate onto giant planets that are growing through gas accretion, using numerical simulations and analytical arguments. We derived the condition for gap opening in the planetesimal disk, which is determined by a competition between the expansion of the planet’s Hill radius due to the planet growth and the damping of planetesimal eccentricity due to ...
متن کاملA vestige low metallicity gas shell surrounding the radio galaxy 0943 – 242 at z = 2 . 92
Observations are presented showing the doublet C ivλλ1548, 1551 absorption lines superimposed on the C iv emission in the radio galaxy 0943–242. Within the errors, the redshift of the absorption system that has a column density of NCIV = 1014.5±0.1 cm−2 coincides with that of the deep Lyα absorption trough observed by Röttgering et al. (1995). The gas seen in absorption has a resolved spatial e...
متن کاملLow Metallicity Stars in Our Galaxy
The advent of 8 m class telescopes has allowed the detailed spectroscopic study of sizeable numbers of extremely metal-poor Galactic stars which are the witnesses of the formation of the early Galaxy. Their chemical composition displays some distinctive trends which should provide a strong constraint on the physical nature of the first generation(s) of stars and on their nucleosynthetic output....
متن کاملRam-Pressure Stripping of Gas from Companions and Accretion onto a Spiral Galaxy: A Gaseous Merger
We simulated the behavior of interstellar gas clouds in a companion galaxy during a gas-dynamical interaction with the halo and disk of a spiral galaxy. By ram pressure, the gas clouds are stripped from the companion, and accreted toward the disk of the spiral galaxy. If the companion’s orbit is retrograde with respect to the rotation of the spiral galaxy, infalling clouds hit the nuclear regio...
