Radial Distribution of the Dust Comae of Comets 45P/Honda-Mrkos-Pajduusáková and 46P/Wirtanen

C. Lejoly, W. Harris, N. Samarasinha +21

There was an unprecedented opportunity to study the inner dust coma environment, where the dust and gas are not entirely decoupled, of comets 45P/Honda-Mrkos-Pajduusáková (45P/HMP)…

Repeating gas ejection events from comet 45P/Honda-Mrkos-Pajdušáková

Alessondra Springmann, Walter M. Harris, Erin L. Ryan +6

Studying materials released from Jupiter-family comets (JFCs) -- as seen in their inner comæ, the envelope of gas and dust that forms as the comet approaches the Sun -- improves th…

Further investigation of changes in cometary rotation

Beatrice E. A. Mueller, Nalin H. Samarasinha

Samarasinha & Mueller (2013) related changes of cometary rotation to other physical parameters for four Jupiter family comets defining a parameter , which is approximately const…

The Excited Spin State of 1I/2017 U1 `Oumuamua

Michael J. S. Belton, Olivier R. Hainaut, Karen J. Meech +15

We show that `Oumuamua's excited spin could be in a high energy LAM state, which implies that its shape could be far from the highly elongated shape found in previous studies. CLEA…

Results from the Worldwide Coma Morphology Campaign for Comet ISON (C/2012 S1)

Nalin H. Samarasinha, 48 co-authors

We present the results of a global coma morphology campaign for comet C/2012 S1 (ISON), which was organized to involve both professional and amateur observers. In response to the c…
