Rotation periods of young brown dwarfs : K2 survey in Upper Scorpius

open access: yes, 2015
This work was supported in part by NSERC grants to R.J.We report rotational periods for 16 young brown dwarfs in the nearby Upper Scorpius association, based on 72 days of high-cadence, high-precision photometry from the Keplerspace telescope's K2 ...

The SOFIA Massive (SOMA) Star Formation Survey. V. Clustered Protostars

open access: yesThe Astrophysical Journal
Abstract We present ∼8–40 μm SOFIA-FORCAST images of seven regions of “clustered” star formation as part of the SOFIA Massive Star Formation Survey. We identify a total of 34 protostar candidates and build their spectral energy distributions (SEDs).

Molecular gas and dust influenced by massive protostars : spectral surveys in the far-infrared and submillimeter [PDF]

open access: yes, 2011
The interstellar gas from which new stars form is crucially influenced by these same 'protostars': gas particles are excited and heated by the protostar.

Dissecting disks around B-type protostars [PDF]

open access: yes, 2013
Recent theoretical models indicate that OB-type stars could form through disk-mediated accretion, like their low mass counterparts. However, on the observational side, circumstellar disks appear still elusive, especially around the most massive (proto ...

Clusters of high-mass protostars: From extreme clouds to mini-bursts of star formation

open access: yes, 2015
Herschel revealed high-density cloud filaments of several pc3, which are forming clusters of OB-type stars. Counting Herschel protostars gives a direct measure of the mass of stars forming in a period of ~105 yrs, the “instantaneous” star formation ...

Observational perspective of the youngest phases of intermediate-mass stars

open access: yes, 2015
Intermediate-mass protostars are the long-forgotten actors in the star-formation scenario. Historically, intermediate-mass stars have been associated to the low-mass regime and not too much attention has been drawn to them as a separate group.
