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 ...
Some like it cold: molecular emission and effective dust temperatures of dense cores in the Pipe Nebula
(2014-08-08)
Aims. The Pipe Nebula is characterized by a low star-formation rate and is therefore an ideal environment to explore how initial conditions, including core characteristics, affect star-formation efficiencies. Methods. In ...
CSI 2264: Simultaneous optical and infrared light curves of young disk-bearing stars in NGC 2264 with CoRoT and Spitzer-- evidence for multiple origins of variability
(2014-03-13)
We present the Coordinated Synoptic Investigation of NGC 2264, a continuous 30-day multi-wavelength photometric monitoring campaign on more than 1000 young cluster members using 16 telescopes. The unprecedented combination ...
