HST NIR Snapshot Survey of 3CR Radio Source Counterparts II: An Atlas and Inventory of the Host Galaxies, Mergers and Companions
David J. E. Floyd, David Axon, Stefi Baum +10
We present the second part of an H-band (1.6 microns) atlas of z<0.3 3CR radio galaxies, using the Hubble Space Telescope Near Infrared Camera and Multi-Object Spectrometer (HST NI…
Constraining Spiral Structure Parameters through Galactic Pencil-beam and Large-scale Radial Velocity Surveys
I. Minchev, A. Quillen
We investigate the effect of spiral structure on the Galactic disk as viewed by pencil beams centered on the Sun, relevant to upcoming surveys such as ARGOS, SEGUE, and GAIA. We cr…
Spitzer IRS mapping of the central kpc of Centaurus A
Alice C. Quillen, Joss Bland-Hawthorn, Joel Green +6
We report on the results of infrared spectroscopic mapping observations carried out in the nuclear region of Centaurus A (NGC5128). The 500 pc bipolar dust shell discovered by Quil…
The Total Number of Giant Planets in Debris Disks with Central Clearings
Peter Faber, Alice C. Quillen
Infrared spectra from the Spitzer Space Telescope (SSC) of many debris disks are well fit with a single black body temperature which suggest clearings within the disk. We assume th…
Planetary embryos and planetesimals residing in thin debris disks
Alice C. Quillen, Alessandro Morbidelli, Alex Moore
We consider constraints on the planetesimal population residing in the disks of AU Microscopii, Beta Pictoris and Fomalhaut taking into account their observed thicknesses and norma…
The Minimum Gap-opening Planet Mass in an Irradiated Circumstellar Accretion Disk
Richard G. Edgar, Alice C. Quillen, Jaehong Park
We consider the minimum mass planet, as a function of radius, that is capable of opening a gap in an -accretion disk. We estimate that a half Jupiter mass planet can open a gap…
New Constraints on the Galactic Bar
I. Minchev, J. Nordhaus, A. C. Quillen
Previous work has related the Galactic Bar to structure in the local stellar velocity distribution. Here we show that the Bar also influences the spatial gradients of the velocity…
Diffusive low optical depth particle disks truncated by planets
Alice C. Quillen
Two dimensional particle disks in proximity to a planet are numerically integrated to determine when a planet in a circular orbit can truncate a particle disk. Collisions are treat…
