Mass transport from the envelope to the disk of V346 Nor: a case study for the luminosity problem in an FUor-type young eruptive star
Á. Kóspál, P. Ábrahám, T. Csengeri +7
A long-standing open issue of the paradigm of low-mass star formation is the luminosity problem: most protostars are less luminous than theoretically predicted. One possible soluti…
A Search For X-ray Emission From Colliding Magnetospheres In Young Eccentric Stellar Binaries
Konstantin V. Getman, Patrick S. Broos, Agnes Kospal +2
Among young binary stars whose magnetospheres are expected to collide, only two systems have been observed near periastron in the X-ray band: the low-mass DQ Tau and the older and…
Extended HCN and HCO emission in the starburst galaxy M82
Pedro Salas, Gaspar Galaz, Demerese Salter +3
We mapped 3 mm continuum and line emission from the starburst galaxy M82 using the Combined Array for Research in Millimeter-wave Astronomy. We targeted the HCN, HCO, HNC, CS…
CARMA Large Area Star Formation Survey: Structure and Kinematics of Dense Gas in Serpens Main
Katherine I. Lee, Manuel Fernandez-Lopez, Shaye Storm +21
We present observations of N2H+(1-0), HCO+(1-0), and HCN(1-0) toward the Serpens Main molecular cloud from the CARMA Large Area Star Formation Survey (CLASSy). We mapped 150 square…
CARMA Large Area Star Formation Survey: Project Overview with Analysis of Dense Gas Structure and Kinematics in Barnard 1
S. Storm, L. G. Mundy, M. Fernández-López +22
We present details of the CARMA Large Area Star Formation Survey (CLASSy), while focusing on observations of Barnard 1. CLASSy is a CARMA Key Project that spectrally imaged N2H+, H…
A single-dish survey of the HCO+, HCN, and CN emission toward the T Tauri disk population in Taurus
D. M. Salter, M. R. Hogerheijde, R. F. J. van der Burg +2
(Abridged) As the stellar X-ray and UV light penetration of a protoplanetary disk depends sensitively on the dust properties, trace molecular species like HCO+, HCN, and CN are exp…
The Young Binary DQ Tau: A Hunt For X-ray Emission From Colliding Magnetospheres
Konstantin V. Getman, Patrick S. Broos, Demerese M. Salter +2
The young high-eccentricity binary DQ Tau exhibits powerful recurring millimeter-band (mm) flaring attributed to collisions between the two stellar magnetospheres near periastron,…
Water in Star-Forming Regions with the Herschel Space Observatory (WISH): Overview of key program and first results
E. F. van Dishoeck, L. E. Kristensen, A. O. Benz +12
`Water In Star-forming regions with Herschel' (WISH) is a key program on the Herschel Space Observatory designed to probe the physical and chemical structure of young stellar objec…
Hunting for millimeter flares from magnetic reconnection in pre-main sequence spectroscopic binaries
Á. Kóspál, D. M. Salter, M. R. Hogerheijde +2
Recent observations of the low-mass pre-main sequence, eccentric spectroscopic binaries DQ Tau and V773 Tau A reveal that their millimeter spectrum is occasionally dominated by fla…
Recurring millimeter flares as evidence for star-star magnetic reconnection events in the DQ Tauri PMS binary system
D. M. Salter, Á. Kóspál, K. V. Getman +5
Observations of the T Tauri spectroscopic binary DQ Tau in April 2008 captured an unusual flare at 3 mm, which peaked at an observed max flux of 0.5 Jy (about 27x the quiescent val…
Grain growth across protoplanetary discs: 10-micron silicate feature versus millimetre slope
Dave J. P. Lommen, Ewine F. van Dishoeck, Chris M. Wright +8
Young stars are formed within dusty discs. The grains in the disc are originally of the same size as interstellar dust. Models predict that these grains will grow in size through c…
A Zero-Gravity Instrument to Study Low Velocity Collisions of Fragile Particles at Low Temperatures
D. M. Salter, D. Heißelmann, G. Chaparro +14
We discuss the design, operation, and performance of a vacuum setup constructed for use in zero (or reduced) gravity conditions to initiate collisions of fragile millimeter-sized p…
The nature of the Class I population in Ophiuchus as revealed through gas and dust mapping
T. A. van Kempen, E. F. van Dishoeck, D. M. Salter +3
The Ophiuchus clouds, in particular L~1688, are an excellent region to study the embedded phases of star formation, due to the relatively large number of protostars. However, the s…
Captured at Millimeter Wavelengths: a Flare from the Classical T Tauri Star DQ Tau
D. M. Salter, M. R. Hogerheijde, G. A. Blake
For several hours on 2008 April 19 the T Tauri spectroscopic binary DQ Tau was observed to brighten, reaching a maximum detected flux of 468 mJy and likely making it (briefly) the…
