Absolute magnitudes and slope parameters for 250,000 asteroids observed by Pan-STARRS PS1 - preliminary results
Peter Vereš, Robert Jedicke, Alan Fitzsimmons +14
We present the results of a Monte Carlo technique to calculate the absolute magnitudes (H) and slope parameters (G) of about 240000 asteroids observed by the Pan-STARRS1 telescope…
The Main-Belt Comets: The Pan-STARRS1 Perspective
Henry H. Hsieh, Larry Denneau, Richard J. Wainscoat +17
We analyze 760475 observations of 333026 main-belt objects obtained by the Pan-STARRS1 (PS1) survey telescope between 2012 May 20 and 2013 November 9, a period during which PS1 dis…
Observational Constraints on the Catastrophic Disruption Rate of Small Main Belt Asteroids
Larry Denneau, Robert Jedicke, Alan Fitzsimmons +15
We have calculated 90% confidence limits on the steady-state rate of catastrophic disruptions of main belt asteroids in terms of the absolute magnitude at which one catastrophic di…
The Extremely Red, Young L Dwarf PSO J318-22: A Free-Floating Planetary-Mass Analog to Directly Imaged Young Gas-Giant Planets
Michael C. Liu, Eugene A. Magnier, Niall R. Deacon +16
We have used Pan-STARRS1 to discover an extremely red late-L dwarf, which has (J-K)_MKO = 2.84 and (J-K)_2MASS = 2.78, making it the reddest known field dwarf and second only to 2M…
Main-Belt Comet P/2012 T1 (PANSTARRS)
Henry H. Hsieh, Heather M. Kaluna, Bojan Novakovic +25
We present initial results from observations and numerical analyses aimed at characterizing main-belt comet P/2012 T1 (PANSTARRS). Optical monitoring observations were made between…
Observational and Dynamical Characterization of Main-Belt Comet P/2010 R2 (La Sagra)
Henry H. Hsieh, Bin Yang, Nader Haghighipour +36
We present observations of comet-like main-belt object P/2010 R2 (La Sagra) obtained by Pan-STARRS 1 and the Faulkes Telescope-North on Haleakala in Hawaii, the University of Hawai…
