Journal ArticleDOI
Probing the Dust and Gas in the Transitional Disk of CS Cha with Spitzer
Catherine Espaillat,Nuria Calvet,Paola D'Alessio,Edwin A. Bergin,Lee Hartmann,Dan M. Watson,Elise Furlan,Joan R. Najita,William J. Forrest,Melissa McClure,Ben Sargent,C. J. Bohac,Samuel T. Harrold +12 more
TL;DR: In this article, the Spitzer IRS spectrum of CS Cha, a member of the ~2 Myr old Chamaeleon star-forming region, was analyzed, revealing an optically thick circumstellar disk truncated at ~43 AU.
Journal ArticleDOI
The CIDA Variability Survey of Orion OB1. I: the low-mass population of Ori OB 1a and 1b
Cesar Briceno,Nuria Calvet,Jesus Hernandez,A. Katherina Vivas,Lee Hartmann,Juan J. Downes,Perry Berlind +6 more
TL;DR: In this paper, a large-scale, multi-epoch optical survey of the Orion OB1 association was carried out with the QuEST camera at the Venezuela National Astronomical Observatory.
Journal ArticleDOI
Long-term evolution of protostellar and protoplanetary disks. I. Outbursts
TL;DR: In this paper, the conditions required to explain the large outbursts of disk accretion seen in some young stellar objects were explored using one-dimensional time-dependent disk models with a phenomenological treatment of the magnetorotational instability (MRI) and gravitational torques.
Journal ArticleDOI
On the formation of multiple concentric rings and gaps in protoplanetary disks
TL;DR: In this paper, the secondary and tertiary arms driven by a planet can also open gaps as they steepen into shocks, and the depths of the secondary/tertiary gaps in surface density grow with time in a low viscosity disk.
Journal ArticleDOI
A Dust Disk Surrounding the Young A Star HR 4796A
Ray Jayawardhana,Ray Jayawardhana,Scott Fisher,Scott Fisher,Lee Hartmann,Charles M. Telesco,Charles M. Telesco,Robert K. Pina,Giovanni G. Fazio +8 more
TL;DR: In this paper, the authors reported the discovery of the spatially resolved dust disk of the Vega-like star HR 4796A, which is a unique system among the β Pictoris stars in that the M star companion is relatively young, ~8 ± 3 Myr.
