Stellar Rotation of T Tauri stars in the Orion Star-Forming Complex
Javier Serna, Jesús Hernández, Marina Kounkel +14
We present a large-scale study of stellar rotation for T Tauri stars in the Orion Star-Forming Complex. We use the projected rotational velocity () estimations reported b…
New Low-Mass Stars in the 25 Orionis Stellar Group and Orion OB1a Sub-association from SDSS-III/BOSS Spectroscopy
Genaro Suárez, Juan José Downes, Carlos Román-Zúñiga +6
The Orion OB1a sub-association is a rich low mass star (LMS) region. Previous spectroscopic studies have confirmed 160 LMSs in the 25 Orionis stellar group (25 Ori), which is the m…
Star Formation Across the W3 Complex
C. G. Román-Zúñiga, J. Ybarra, G. Megias +3
We present a multi-wavelength analysis of the history of star formation in the W3 complex. Using deep, near-infrared ground-based images, combined with images obtained with Spitzer…
Spitzer IRAC Color Diagnostics for Extended Emission in Star Forming Regions
Jason E. Ybarra, Mauricio Tapia, Carlos G. Román-Zúñiga +1
The infrared data from the Spitzer Space Telescope has provided an invaluable tool for identifying physical processes in star formation. In this study we calculate the IRAC color s…
Periodic Radio Continuum Emission Associated with the beta Cephei Star V2187 Cyg
Mauricio Tapia, Luis F. Rodriguez, Gagik Tovmassian +4
We present new optical time-resolved photometry and medium-resolution spectroscopy of V2187 Cyg. We confirm its classification as a beta Cephei star based on sinusoidal light varia…
Extended Non-Thermal Emission Possibly Associated with Cyg OB2 #5
G. N. Ortiz-Leon, L. F. Rodriguez, M. Tapia
Cyg OB2 #5 is a contact binary system (O6.5-7+O5.5-6) with associated radio continuum emission. Two compact () radio continuum components have been reported previ…
SDSS J123813.73-033933.0, a cataclysmic variable evolved beyond the period minimum
A. Aviles, S. Zharikov, G. Tovmassian +12
We present infrared JHK photometry of the cataclysmic variable SDSS J123813.73-033933.0 (SDSS1238)and analyze it along with optical spectroscopy, demonstrating that the binary syst…
Orbitally modulated dust formation by the WC7+O5 colliding-wind binary WR140
P. M. Williams, S. V. Marchenko, A. P. Marston +6
We present high-resolution infrared (2--18 micron) images of the archetypal periodic dust-making Wolf-Rayet binary system WR140 (HD 193793) taken between 2001 and 2005, and multi-c…
