TESSExtractor: A web-based interactive tool for light-curve visualisation and period estimation using TESS full-frame images
Javier Serna, Jesús Hernández, Sean P. Matt +23
We present a user-friendly web application that allows users to extract, visualise, and interact with TESS light-curves (LCs) from full-frame images. The service works for any star…
Stellar Properties for a Comprehensive Collection of Star Forming Regions in the SDSS APOGEE-2 Survey
Carlos G. Román-Zúñiga, Marina Kounkel, Jesús Hernández +25
The Sloan Digital Sky Survey IV (SDSS-IV) APOGEE-2 primary science goal was to observe red giant stars throughout the Galaxy to study its dynamics, morphology, and chemical evoluti…
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…
An infrared study of the high-mass, multi-stage star-forming region IRAS~12272-6240
Mauricio Tapia, Paolo Persi, Miguel Roth +1
IRAS 12272-6240 is a complex star forming region with a compact massive dense clump and several associated masers, located at a well-determined distance of kpc from the Sun…
Evidence of Hubble flow-like motion of young stellar populations away from the Perseus arm
Carlos Román-Zúñiga, Alexandre Roman-Lopes, Mauricio Tapia +2
In this letter we present evidence of coherent outward motion of a sample of young stars (30 Myr) in the Perseus Arm, whose apparent origin is located in the vicinity of the W3…
Massive stars in the SDSS-IV/APOGEE SURVEY. I- OB stars
A. Roman-Lopes, C. RomÁn-ZÚÑiga, Mauricio Tapia +10
In this work we make use of DR14 APOGEE spectroscopic data to study a sample of 92 known OB stars. We developed a near-infrared semi-empirical spectral classification method that w…
The richness of compact radio sources in NGC 6334D to F
S. -N. X. Medina, S. A. Dzib, M. Tapia +2
The presence and properties of compact radio sources embedded in massive star-forming regions can reveal important physical properties about these regions and the processes occurri…
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…
The Peculiar Radio Source M17 JVLA 35
L. F. Rodriguez, C. Carrasco-Gonzalez, G. Montes +1
M17 JVLA 35 is a radio source detected in projection against the M17 HII region. In recent observations, its spectrum between 4.96 and 8.46 GHz was found to be positive and very st…
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
