TL;DR: The Stratospheric Observatory for Infrared Astronomy (SOFIA) is an airborne observatory consisting of a specially modified Boeing 747SP with a 2.7 m telescope, flying at altitudes as high as 13.7 km (45,000 ft) as discussed by the authors.

TL;DR: In this paper, the first disk-mediated accretion burst from a roughly twenty-solar-mass high-mass young stellar object was detected in near-infrared images.
Journal ArticleDOI
First Detection of Millimeter Dust Emission from Brown Dwarf Disks
TL;DR: In this paper, the first deep millimeter continuum survey targeting brown dwarfs (BDs) was conducted, which led to the first detection of cold dust in the disks around two young BDs (CFHT-BD-Tau 4 and IC 348 613).
Journal ArticleDOI
A millimeter continuum survey for massive protoclusters in the outer Galaxy
TL;DR: In this paper, a search for the earliest stages of massive star formation turned up 12 massive pre-protocluster candidates plus a few protoclusters, which were identified by the lack of detections in the above-mentioned nearinfrared, mid-infrared and radio surveys.
Journal ArticleDOI

TL;DR: The Rossi X-Ray Timing Explorer (RXTE) was used to detect quasi-periodic X-ray brightness oscillations (QPOs) at 20, 40, and 60 Hz as mentioned in this paper.
