Theory of Disk Accretion onto Magnetic Stars

open access: yesEPJ Web of Conferences, 2014
Disk accretion onto magnetic stars occurs in a variety of systems, including accreting neutron stars (with both high and low magnetic fields), white dwarfs, and protostars.

Centimeter Polarimetry of the R Coronae Australis Region

open access: yes, 2008
Circularly polarized 3.5 cm continuum emission was detected toward three radio sources in the R CrA region using the Very Large Array. The Class I protostar IRS 5b persistently showed polarized radio emission with a constant helicity over 8 yr, which ...

IPA: Class 0 Protostars Viewed in CO Emission Using JWST

open access: yesThe Astrophysical Journal
We investigate the bright CO fundamental emission in the central regions of five protostars in their primary mass assembly phase using new observations from JWST’s Near-Infrared Spectrograph and Mid-Infrared Instrument. CO line emission images and fluxes

Infrared emission from protostars

open access: yesThe Astrophysical Journal, 1985
The emergent spectral energy distribution at infrared to radio wavelengths is calculated for the simplest theoretical construct of a low-mass protostar. It is shown that the emergent spectrum in the infrared is insensitive to the details assumed for the temperature profile as long as allowance is made for a transition from optically thick to optically ...

Mass and luminosity evolution of young stellar objects

open access: yes, 2012
A model of protostar mass and luminosity evolution in clusters gives new estimates of cluster age, protostar birthrate, accretion rate and mean accretion time.

Effect of Magnetic Field on the Accretion Phase of Population III Star Formation

open access: yesThe Astrophysical Journal
We examine the impact of the magnetic field on Population III star formation by varying its strength. We perform simulations with magnetic field strengths ranging from 10 ^−20 G to 10 ^−4 G, in addition to a model without a magnetic field.

2-D and 3-D Radiation Transfer Models of High-Mass Star Formation

open access: yes, 2005
2-D and 3-D radiation transfer models of forming stars generally produce bluer 1-10 micron colors than 1-D models of the same evolutionary state and envelope mass.

ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Molecular Jets and Episodic Accretion in Protostars

open access: yesThe Astronomical Journal
Protostellar outflows and jets are almost ubiquitous characteristics during the mass accretion phase and encode the history of stellar accretion, complex organic molecule (COM) formation, and planet formation.
