The JCMT Transient Survey: An Extraordinary Submillimeter Flare in the T Tauri Binary System JW 566
(2019-01-23)
The binary T Tauri system JW 566 in the Orion Molecular Cloud underwent an energetic, short-lived flare observed at submillimetre wavelengths by the SCUBA-2 instrument on 26 November 2016 (UT). The emission faded by nearly ...
Meter- to Millimeter Emission from Cool Stellar Systems : Latest Results, Synergies Across the Spectrum, and Outlook for the Next Decade
(2018-11-01)
Radio observations of cool stellar systems provide unique information on their magnetic fields, high-energy processes, and chemistry. Buoyed by powerful new instruments (e.g. ALMA, JVLA, LOFAR), advances in related fields ...
VISION - Vienna survey in Orion. III. Young stellar objects in Orion A
(2018-09-30)
We extend and refine the existing young stellar object (YSO) catalogs for the Orion A molecular cloud, the closest massive star-forming region to Earth. This updated catalog is driven by the large spatial coverage (18.3 ...
How do stars gain their mass? : A JCMT/SCUBA-2 Transient Survey of Protostars in Nearby Star Forming Regions
(2017-10-27)
Most protostars have luminosities that are fainter than expected from steady accretion over the protostellar lifetime. The solution to this problem may lie in episodic mass accretion -- prolonged periods of very low accretion ...
The Population of Compact Radio Sources in the Orion Nebula Cluster
(2016-05-10)
We present a deep centimeter-wavelength catalog of the Orion Nebula Cluster (ONC), based on a 30h single-pointing observation with the Karl G. Jansky Very Large Array in its high-resolution A-configuration using two 1 GHz ...
VISION - Vienna survey in Orion I. VISTA Orion A Survey
(2016-03-07)
Orion A hosts the nearest massive star factory, thus offering a unique opportunity to resolve the processes connected with the formation of both low- and high-mass stars. Here we present the most detailed and sensitive ...
Radio monitoring of the periodically variable IR source LRLL 54361: No direct correlation between the radio and IR emissions
(2015-11-12)
LRLL 54361 is an infrared source located in the star forming region IC 348 SW. Remarkably, its infrared luminosity increases by a factor of 10 during roughly one week every 25.34 days. To understand the origin of these ...
Smoke in the Pipe Nebula: dust emission and grain growth in the starless core FeSt 1-457
(2015-08-13)
(abridged) Methods: We derive maps of submillimeter dust optical depth and effective dust temperature from Herschel data that were calibrated against Planck. After calibration, we then fit a modified blackbody to the ...
Tomography of Galactic star-forming regions and spiral arms with the Square Kilometer Array
(Proceedings of Science (PoS), 2014-12-19)
Very Long Baseline Interferometry (VLBI) at radio wavelengths can provide astrometry accurate to 10 micro-arcseconds or better (i.e. better than the target GAIA accuracy) without being limited by dust obscuration. This ...
Constraints on photoevaporation models from (lack of) radio emission in the Corona Australis protoplanetary disks
(2014-10-21)
Photoevaporation due to high-energy stellar photons is thought to be one of the main drivers of protoplanetary disk dispersal. The fully or partially ionized disk surface is expected to produce free-free continuum emission ...
