On the rotation period and shape of the hyperbolic asteroid 1I/`Oumuamua (2017) U1 from its lightcurve
Matthew M. Knight, Silvia Protopapa, Michael S. P. Kelley +5
We observed the newly discovered hyperbolic minor planet 1I/`Oumuamua (2017 U1) on 2017 October 30 with Lowell Observatory's 4.3-m Discovery Channel Telescope. From these observati…
FUV Spectral Signatures of Molecules and the Evolution of the Gaseous Coma of Comet 67P/Churyumov-Gerasimenko
Paul D. Feldman, Michael F. A'Hearn, Jean-Loup Bertaux +10
The Alice far-ultraviolet imaging spectrograph onboard Rosetta observed emissions from atomic and molecular species from within the coma of comet 67P/Churyumov-Gerasimenko during t…
Evidence of sub-surface energy storage in comet 67P from the outburst of 2016 July 3
J. Agarwal, V. Della Corte, P. D. Feldman +67
On 3 July 2016, several instruments on board ESA's Rosetta spacecraft detected signs of an outburst event on comet 67P, at a heliocentric distance of 3.32 AU from the sun, outbound…
Near-UV OH Prompt Emission in the Innermost Coma of 103P/Hartley 2
Fiorangela La Forgia, Dennis Bodewits, Michael F. A'Hearn +5
The Deep Impact spacecraft fly-by of comet 103P/Hartley 2 occurred on 2010 November 4, one week after perihelion with a closest approach (CA) distance of about 700 km. We used narr…
HO and O Absorption in the Coma of Comet 67P/Churyumov-Gerasimenko Measured by the Alice Far-Ultraviolet Spectrograph on Rosetta
Brian A. Keeney, S. Alan Stern, Michael F. A'Hearn +10
We have detected HO and O absorption against the far-UV continuum of stars located on lines of sight near the nucleus of Comet 67P/Churyumov-Gerasimenko using the Alice ima…
The 67P/Churyumov-Gerasimenko observation campaign in support of the Rosetta mission
C. Snodgrass, M. F. A'Hearn, F. Aceituno +112
We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67…
