Spitzer Observations of Interstellar Object 1I/`Oumuamua
DE Trilling, M Mommert, JL Hora +20
1I/`Oumuamua is the first confirmed interstellar body in our Solar System. Here we report on observations of `Oumuamua made with the Spitzer Space Telescope on 2017 November 21--22…
Extreme asteroids in the Pan-STARRS 1 Survey
Andrew McNeill, Alan Fitzsimmons, Robert Jedicke +7
Using the first 18 months of the Pan-STARRS 1 survey we have identified 33 candidate high-amplitude objects for follow-up observations and carried out observations of 22 asteroids.…
Main Belt Asteroid Shape Distribution from Gaia DR2
Michael Mommert, Andrew McNeill, David E. Trilling +2
Gaia Data Release 2 includes observational data for 14,099 pre-selected asteroids. From the sparsely sampled G band photometry, we derive lower-limit lightcurve amplitudes for 11,6…
Infrared Lightcurves of Near Earth Objects
Joseph L. Hora, Amir Siraj, Michael Mommert +9
We present lightcurves and derive periods and amplitudes for a subset of 38 near earth objects (NEOs) observed at 4.5 microns with the IRAC camera on the the Spitzer Space Telescop…
Taxonomy and Light-Curve Data of 1000 Serendipitously Observed Main-Belt Asteroids
N. Erasmus, A. McNeill, M. Mommert +3
We present VRI spectrophotometry of 1003 Main-Belt Asteroids (MBAs) observed with the Sutherland, South Africa, node of the Korea Microlensing Telescope Network (KMTNet). All of th…
Constraints on the Density and Internal Strength of 1I/'Oumuamua
Andrew McNeill, David E. Trilling, Michael Mommert
1I/'Oumuamua was discovered by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS 1) on 19 October 2017. Unlike all previously discovered minor planets this objec…
