Disentangling Planets from Photoelectric Instability in Gas-Rich Optically Thin Dusty Disks
Areli Castrejon, Wladimir Lyra, Alexander J. W. Richert +1
Structures in circumstellar disks such as gaps and rings are often attributed to planets. This connection has been difficult to show unequivocally, as other processes may also prod…
Circumstellar Disk Lifetimes In Numerous Galactic Young Stellar Clusters
Alexander J. W. Richert, Konstantin V. Getman, Eric D. Feigelson +5
Photometric detections of dust circumstellar disks around pre-main sequence (PMS) stars, coupled with estimates of stellar ages, provide constraints on the time available for plane…
The interplay between radiation pressure and the photoelectric instability in optically thin disks of gas and dust
Alexander J. W. Richert, Wladimir Lyra, Marc Kuchner
Previous theoretical works have shown that in optically thin disks, dust grains are photoelectrically stripped of electrons by starlight, heating nearby gas and possibly creating a…
Star Formation In Nearby Clouds (SFiNCs): X-ray And Infrared Source Catalogs And Membership
Konstantin V. Getman, Patrick S. Broos, Michael A. Kuhn +5
The Star Formation in Nearby Clouds (SFiNCs) project is aimed at providing detailed study of the young stellar populations and star cluster formation in nearby 22 star forming regi…
On shocks driven by high-mass planets in radiatively inefficient disks. II. Three-dimensional global disk simulations
Wladimir Lyra, Alexander J. W. Richert, Aaron Boley +4
Recent high-resolution, near-infrared images of protoplanetary disks have shown that these disks often present spiral features. Spiral arms are among the structures predicted decad…
No evidence for protoplanetary disk destruction by OB stars in the MYStIX sample
Alexander J. W. Richert, Eric D. Feigelson, Konstantin V. Getman +1
HST images of proplyds in the Orion Nebula, as well as submillimeter/radio measurements, show that the dominant O7 star Theta1 Ori C photoevaporates nearby disks around pre-main se…
On shocks driven by high-mass planets in radiatively inefficient disks. I. Two-dimensional global disk simulations
Alexander J. W. Richert, Wladimir Lyra, Aaron Boley +2
Recent observations of gaps and non-axisymmetric features in the dust distributions of transition disks have been interpreted as evidence of embedded massive protoplanets. However,…
Near-IR Direct Detection of Water Vapor in Tau Boo b
Alexandra C. Lockwood, John A. Johnson, Chad F. Bender +4
We use high dynamic range, high-resolution L-band spectroscopy to measure the radial velocity variations of the hot Jupiter in the tau Bootis planetary system. The detection of an…
KELT-6b: A P~7.9 d Hot Saturn Transiting a Metal-Poor Star with a Long-Period Companion
Karen A. Collins, Jason D. Eastman, Thomas G. Beatty +39
We report the discovery of KELT-6b, a mildly-inflated Saturn-mass planet transiting a metal-poor host. The initial transit signal was identified in KELT-North survey data, and the…
KELT-3b: A Hot Jupiter Transiting a V=9.8 Late-F Star
Joshua Pepper, Robert J. Siverd, Thomas G. Beatty +31
We report the discovery of KELT-3b, a moderately inflated transiting hot Jupiter with a mass of 1.477 (-0.067, +0.066) M_J, and radius of 1.345 +/- 0.072 R_J, with an orbital perio…
