Constraining the Dust Coma Properties of Comet C/Siding Spring (2013 A1) at Large Heliocentric Distances
Jian-Yang Li, Nalin H. Samarasinha, Michael S. P. Kelley +5
The close encounter of Comet C/2013 A1 (Siding Spring) with Mars on October 19, 2014 presented an extremely rare opportunity to obtain the first flyby quality data of the nucleus a…
A Study of Dust and Gas at Mars from Comet C/2013 A1 (Siding Spring)
Michael S. P. Kelley, Tony L. Farnham, Dennis Bodewits +2
Although the nucleus of comet C/2013 A1 (Siding Spring) will safely pass Mars in October 2014, the dust in the coma and tail will more closely approach the planet. Using a dynamica…
Water Ice and Dust in the Innermost Coma of Comet 103P/Hartley 2
Silvia Protopapa, Jessica M. Sunshine, Lori M. Feaga +7
On November 4th, 2010, the Deep Impact eXtended Investigation (DIXI) successfully encountered comet 103P/Hartley 2, when it was at a heliocentric distance of 1.06 AU. Spatially res…
Properties of comet 9P/Tempel 1 dust immediately following excavation by Deep Impact
Lev Nagdimunov, Ludmilla Kolokolova, Michael Wolff +2
We analyzed Deep Impact High Resolution Instrument (HRI) images acquired within the first seconds after collision of the Deep Impact impactor with the nucleus of comet 9P/Tempel 1.…
Delivery of dust grains from comet C/2013 A1 (Siding Spring) to Mars
Pasquale Tricarico, Nalin H. Samarasinha, Mark V. Sykes +7
Comet C/2013 A1 (Siding Spring) will have a close encounter with Mars on October 19, 2014. We model the dynamical evolution of dust grains from the time of their ejection from the…
Trajectory analysis for the nucleus and dust of comet C/2013~A1 (Siding Spring)
Davide Farnocchia, Steven R. Chesley, Paul W. Chodas +3
Comet C/2013 A1 (siding Spring) will experience a high velocity encounter with Mars on October 19, 2014 at a distance of 135,000 km +- 5000 km from the planet center. We present a…
The Evolving Activity of the Dynamically Young Comet C/2009 P1 (Garradd)
D. Bodewits, T. L. Farnham, M. F. A'Hearn +4
We used the UltraViolet-Optical Telescope on board Swift to observe the dynamically young comet C/2009 P1 (Garradd) from a heliocentric distance of 3.5 AU pre-perihelion until 4.0…
