Outbursts of young stellar objects [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
We argue that the outbursts of the FU Orionis stars occur on timescales which are much longer than expected from the standard disc instability model with α_{c} \gtrsim 10^{-3}. The outburst, recurrence, and rise times are consistent with the idea that the accretion disc in these objects is truncated at a radius R_{i} \sim 40 \rsun.

YOUNG STELLAR OBJECTS IN THE GOULD BELT [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2015
We present the full catalog of Young Stellar Objects (YSOs) identified in the 18 molecular clouds surveyed by the Spitzer Space Telescope "cores to disks" (c2d) and "Gould Belt" (GB) Legacy surveys. Using standard techniques developed by the c2d project, we identify 3239 candidate YSOs in the 18 clouds, 2966 of which survive visual inspection and form ...

Young stellar objects close to Sgr A* [PDF]

open access: yesProceedings of the International Astronomical Union, 2013
AbstractWe aim at modeling small groups of young stars such as IRS 13N, 0.1 pc away from Sgr A*, which is suggested to contain a few embedded massive young stellar objects. We perform hydrodynamical simulations to follow the evolution of molecular clumps orbiting around a 4 × 106 M⊙ black hole, to constrain the formation and the physical conditions of ...

YOUNG STELLAR CLUSTERS CONTAINING MASSIVE YOUNG STELLAR OBJECTS IN THE VVV SURVEY [PDF]

open access: yesThe Astronomical Journal, 2016
ABSTRACT The purpose of this research is to study the connections of the global properties of eight young stellar clusters projected in the Vista Variables in the Via Lactea (VVV) ESO Large Public Survey disk area and their young stellar object (YSO) populations.

External Photoevaporation of Disks around Low Mass Young Stellar and Sub-Stellar Objects

open access: yes, 2021
External UV environment of stellar nurseries plays a major role on evolution of protoplanetary disks around young stellar objects. Photoevaporating protoplanetary disks (proplyds) have been found mainly around O stars in strong radiation environments ...

Study of young stellar objects and associated filamentary structures in the inner Galaxy [PDF]

open access: yes, 2013
Young Stellar Objects (YSOs) in the inner Galactic region 100 < l < 150 and −10 < b < 10 are studied using GLIMPSE images and GLIMPSE data catalogue.

The GRAVITY young stellar object survey

open access: yesAstronomy & Astrophysics, 2019
Contexto. Los estudios de la distribución del polvo, la composición y la evolución de los discos protoplanetarios proporcionan pistas para comprender la formación de planetas. Sin embargo, se sabe poco sobre las regiones más internas de los discos donde se espera que se formen los planetas telúricos. Objetivos.

Infrared Interferometric Observations of Young Stellar Objects [PDF]

open access: yesThe Astrophysical Journal, 2000
We present infrared observations of four young stellar objects using the Palomar Testbed Interferometer (PTI). For three of the sources, T Tau, MWC 147 and SU Aur, the 2.2 micron emission is resolved at PTI's nominal fringe spacing of 4 milliarcsec (mas), while the emission region of AB Aur is over-resolved on this scale.
