Centaur Nuclei: Sizes, Shapes, Spins, and Structure

Y. R. Fernandez, M. W. Buie, P. Lacerda +1

We present a wide-ranging but in-depth analysis of Centaurs, focusing on their physical and structural aspects. Centaurs, originating from the Scattered Disk and Kuiper Belt, play…

Secular brightness curves of 272 comets

P. Lacerda, A. Guilbert-Lepoutre, R . Kokotanekova +3

We investigate the brightening behavior of long-period comets as a function of dynamical age, defined by the original reciprocal semimajor axis, . Our goal is to test long-s…

How much earlier would LSST have discovered currently known long-period comets?

Laura Inno, Margherita Scuderi, Ivano Bertini +10

Among solar system objects, comets coming from the Oort Cloud are an elusive population, intrinsically rare and difficult to detect. Nonetheless, as the more pristine objects we ca…

Implications of the Small Spin Changes Measured for Large Jupiter-Family Comet Nuclei

Rosita Kokotanekova, Colin Snodgrass, Pedro Lacerda +3

Rotational spin-up due to outgassing of comet nuclei has been identified as a possible mechanism for considerable mass-loss and splitting. We report a search for spin changes for t…

Comet formation in collapsing pebble clouds. What cometary bulk density implies for the cloud mass and dust-to-ice ratio

S. Lorek, B. Gundlach, P. Lacerda +1

Comets are remnants of the icy planetesimals that formed beyond the ice line in the Solar Nebula. Growing from micrometre-sized dust and ice particles to km-sized objects is, howev…

Discovery of Main-Belt Comet P/2006 VW139 by Pan-STARRS1

Henry H. Hsieh, Bin Yang, Nader Haghighipour +39

Main belt asteroid (300163) 2006 VW139 (later designated P/2006 VW139) was discovered to exhibit comet-like activity by the Pan-STARRS1 survey telescope using automated point-sprea…

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…
