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 new search for variable stars in the globular cluster NGC 6366
A. Arellano Ferro, Sunetra Giridhar, V. Rojas Lopez +3
New CCD photometry of NGC 6366 has lead to the discovery of some variable stars. Two possible Anomalous Cepheids (or Pop II Cepheids), three long period variables, one SX Phe and o…
Secular Light Curve of 2P/Encke: A Comet Active At Aphelion
Ignacio Ferrin
We present the secular light curve of comet 2P/Encke in two phase spaces, the log plot, and the time plot. The main conclusions of this work are: a) The comet shows activity at per…
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…
On the Diversity of the Taurus Transitional Disks: UX Tau A & Lk Ca 15
C. Espaillat, N. Calvet, P. D'Alessio +5
The recently recognized class of "transitional disk" systems consists of young starswith optically-thick outer disks but inner disks which are mostly devoid of small dust. Here we…
The Hot Inner Disk of FU Ori
Zhaohuan Zhu, Lee Hartmann, Nuria Calvet +3
We have constructed a detailed radiative transfer disk model which reproduces the main features of the spectrum of the outbursting young stellar object FU Orionis from ~ 4000 angst…
