Initial characterization of interstellar comet 2I/Borisov [PDF]

Nature Astronomy, 2019
Interstellar comets penetrating through the Solar System had been anticipated for decades 1 , 2 . The discovery of asteroidal-looking ‘Oumuamua 3 , 4 was thus a huge surprise and a puzzle.

Photometry of comet C/2011 L4 (PANSTARRS) at 4.4 - 4.2 AU heliocentric distances

, 2014
We present an analysis of the photometric data of comet C/2011 L4 (PANSTARRS) observed at heliocentric distance of 4.4 - 4.2 AU. The comet C/2011 L4 (PANSTARRS) shows one significant activity, despite of its quite large heliocentric distance.

The Peculiar Volatile Composition of CO-dominated Comet C/2016 R2 (PanSTARRS) [PDF]

Astronomical Journal, 2019
Comet C/2016 R2 (PanSTARRS) has a peculiar volatile composition, with CO being the dominant volatile, as opposed to H2O, and one of the largest N2/CO ratios ever observed in a comet.

Effects of the Planar Galactic Tides and Stellar Mass on Comet Cloud Dynamics

, 2009
We report the first results of a research program to explore the sensitivity of the orbits of Oort cloud comets to changes in the strength of the Galactic tides in the plane of the disk and also to changes in the mass of the host star.

Spitzer Space Telescope Observations of the Nucleus of Comet 103P/Hartley 2 [PDF]

, 2009
We have used the Spitzer Space Telescope InfraRed Spectrograph (IRS) 22-μm peakup array to observe thermal emission from the nucleus and trail of comet 103P/Hartley 2, the target of NASA’s Deep Impact Extended Investigation (DIXI). The comet was observed

The Dust Trail of Comet 67P/Churyumov-Gerasimenko

, 2007
We report the detection of comet 67P/Churyumov-Gerasimenko's dust trail and nucleus in 24 micron Spitzer Space Telescope images taken February 2004. The dust trail is not found in optical Palomar images taken June 2003.

Nature and Nurture: a model for soft gamma-ray repeaters [PDF]

, 2000
During supernova explosions, strange stars with almost bare quark surfaces may be formed. Under certain conditions, these stars could be rapidly spun down by the torque exerted by the fossil disks formed from the fall-back materials.

Simultaneous Observation of Negatively and Positively Charged Nanograins at Comet 67P/Churyumov‐Gerasimenko

Geophysical Research Letters, 2020
Observations near comet 67P by Rosetta show evidence of charged nanograins. Specifically, the ion and electron sensor (IES) observed negative particles with energy/charge (E/q) consistent with charged nanograins.
