Masses and Implications for Ages of Low-Mass Pre-Main Sequence Stars in Taurus and Ophiuchus
M. Simon, S. Guilloteau, Tracy L. Beck +6
The accuracy of masses of pre-main sequence (PMS) stars derived from their locations on the Hertzsprung-Russell Diagram (HRD) can be tested by comparison with accurate and precise…
Dynamical Masses of Low Mass Stars in the Taurus and Ophiuchus Star Forming Regions
M. Simon, S. Guilloteau, E. di Folco +8
We report new dynamical masses for 5 pre-main sequence (PMS) stars in the L1495 region of the Taurus star-forming region (SFR) and 6 in the L1688 region of the Ophiuchus SFR. Since…
The Flying Saucer: Tomography of the thermal and density gas structure of an edge-on protoplanetary disk
A. Dutrey, S. Guilloteau, V. Piétu +10
Determining the gas density and temperature structures of protoplanetary disks is a fundamental task to constrain planet formation theories. This is a challenging procedure and mos…
The shadow of the Flying Saucer: A very low temperature for large dust grains
S. Guilloteau, V. Piétu, E. Chapillon +6
Dust determines the temperature structure of protoplanetary disks. However, dust temperature determinations almost invariably rely on a complex modeling of the Spectral Energy Dist…
Sensitive survey for 13CO, CN, H2CO, and SO in the disks of T Tauri and Herbig Ae stars II: Stars in Oph and upper Scorpius
L. Reboussin, S. Guilloteau, M. Simon +5
We attempt to determine the molecular composition of disks around young low-mass stars in the Oph region and to compare our results with a similar study performed in the Taurus…
Gas physical conditions and kinematics of the giant outflow Ou4
Romano L. M. Corradi, Nicolas Grosso, Agnès Acker +2
Ou4 is a recently discovered bipolar outflow with a projected size of more than one degree in the plane of the sky. It is apparently centred on the young stellar cluster -whose mos…
Episodic Accretion in Young Stars
Marc Audard, Péter Ábrahám, Michael M. Dunham +10
In the last twenty years, the topic of episodic accretion has gained significant interest in the star formation community. It is now viewed as a common, though still poorly underst…
Star Formation in Orion's L1630 Cloud: an Infrared and Multi-epoch X-ray Study
David A. Principe, Joel H. Kastner, Nicolas Grosso +4
X-ray emission is characteristic of young stellar objects (YSOs) and is known to be highly variable. We investigate, via an infrared and multi-epoch X-ray study of the L1630 dark c…
Detection of a Cool, Accretion Shock-Generated X-ray Plasma in EX Lupi During the 2008 Optical Eruption
William K. Teets, David A. Weintraub, Joel H. Kastner +3
EX Lupi is the prototype for a class of young, pre-main sequence stars which are observed to undergo irregular, presumably accretion-generated, optical outbursts that result in a s…
Suzaku Observation of Strong Fluorescent Iron Line Emission from the Young Stellar Object V1647 Ori during Its New X-ray Outburst
Kenji Hamaguchi, Nicolas Grosso, Joel H. Kastner +2
The Suzaku X-ray satellite observed the young stellar object V1647 Ori on 2008 October 8 during the new mass accretion outburst reported in August 2008. During the 87 ksec observat…
X-raying the Beating Heart of a Newborn Star: Rotational Modulation of High-energy Radiation from V1647 Ori
Kenji Hamaguchi, Nicolas Grosso, Joel H. Kastner +5
We report a periodicity of ~1 day in the highly elevated X-ray emission from the protostar V1647 Ori during its two recent multiple-year outbursts of mass accretion. This periodici…
X-ray Production by V1647 Ori During Optical Outbursts
William K. Teets, David A. Weintraub, Nicolas Grosso +4
The pre-main sequence star V1647 Ori has recently undergone two optical/near-infrared (OIR) outbursts that are associated with dramatic enhancements in the stellar accretion rate.…
A sparse population of young stars in Cepheus
A. Klutsch, D. Montes, P. Guillout +5
Once mixed in the ambient galactic plane stellar population, young stars are virtually indiscernible because neither their global photometric properties nor the presence of nearby…
Chandra X-ray Detection of the Enigmatic Field Star BP Psc
Joel H. Kastner, Rodolfo Montez, David Rodriguez +5
BP Psc is a remarkable emission-line field star that is orbited by a dusty disk and drives a parsec-scale system of jets. We report the detection by the Chandra X-ray Observatory o…
A few days before the end of the 2008 extreme outburst of EX Lup : accretion shocks and a smothered stellar corona unveiled by XMM-Newton
Nicolas Grosso, Kenji Hamaguchi, Joel H. Kastner +2
In mid-January 2008, EX Lup, the prototype of the small class of eruptive variables called EXors, began an extreme outburst that lasted seven months. We observed EX Lup during abou…
C2D Spitzer-IRS spectra of disks around T Tauri stars V. Spectral decomposition
J. Olofsson, J. -C. Augereau, E. F. van Dishoeck +5
(Abridged) Dust particles evolve in size and lattice structure in protoplanetary disks, due to coagulation, fragmentation and crystallization, and are radially and vertically mixed…
Results from DROXO. III. Observation, source list and X-ray properties of sources detected in the "Deep Rho Ophiuchi XMM-Newton Observation"
I. Pillitteri, S. Sciortino, E. Flaccomio +8
X-rays from very young stars are powerful probes to investigate the mechanisms at work in the very first stages of the star formation and the origin of X-ray emission in very young…
The Taurus Spitzer Survey: New Candidate Taurus Members Selected Using Sensitive Mid-Infrared Photometry
L. M. Rebull, D. L. Padgett, C. -E. McCabe +31
We report on the properties of pre-main-sequence objects in the Taurus molecular clouds as observed in 7 mid- and far-infrared bands with the Spitzer Space Telescope. There are 215…
