Disks around Brown Dwarfs in the Sigma Orionis Cluster
K. L. Luhman, J. Hernandez, J. J. Downes +2
We have performed a census of disks around brown dwarfs in the Sigma Ori cluster using all available images from IRAC onboard the Spitzer Space Telescope. To search for new low-mas…
A large-scale optical-near infrared survey for brown dwarfs and very low-mass stars in the Orion OB1 association
Juan José Downes, César Briceño, Jesús Hernández +3
We report the initial results of a large-scale optical-near infrared survey to extend the known young population of the entire Orion star-forming region down to the substellar doma…
Spitzer observations of the Orion OB1 association: disk census in the low mass stars
Jesus Hernandez, Nuria Calvet, C. Briceno +6
We present new Spitzer Space Telescope observations of two fields in the Orion OB1 association. We report here IRAC/MIPS observations for 115 confirmed members and 41 photometric c…
OPserver: interactive online-computations of opacities and radiative accelerations
C. Mendoza, M. J. Seaton, P. Buerger +8
Codes to compute mean opacities and radiative accelerations for arbitrary chemical mixtures using the Opacity Project recently revised data have been restructured in a client--serv…
Searching for RR Lyrae stars in the Canis Major Overdensity
Cecilia Mateu, A. Katherina Vivas, Robert Zinn +2
The Canis Major overdensity (CMa) was initially proposed to be the remnant of a tidally disrupting dSph galaxy. Since its nature is still subject of debate, the goal of the present…
The CIDA Variability Survey of Orion OB1. I: the low-mass population of Ori OB 1a and 1b
Cesar Briceno, Nuria Calvet, Jesus Hernandez +4
We present results of a large scale, multi-epoch optical survey of the Ori OB1 association, carried out with the QuEST camera at the Venezuela National Astronomical Observatory. We…
Discovery of the Optical Transient of the Gamma Ray Burst 990308
Bradley E. Schaefer, J. A. Snyder, J. Hernandez +53
The optical transient of the faint Gamma Ray Burst 990308 was detected by the QUEST camera on the Venezuelan 1-m Schmidt telescope starting 3.28 hours after the burst. Our photomet…
