Investigation of Split Comet 240P/NEAT
David Jewitt, Jane Luu, Yoonyoung Kim
We present time-series observations of the split comet 240P/NEAT near perihelion, obtained using the Nordic Optical Telescope. The brighter component, 240P-A, has an estimated radi…
Comet 108P/Ciffreo: The Blob
Yoonyoung Kim, David Jewitt, Jane Luu +2
Short-period comet 108P/Ciffreo is known for its peculiar double morphology, in which the nucleus is accompanied by a co-moving, detached, diffuse 'blob'. We report new observation…
Rotational Mass Shedding from Asteroid (6478) Gault
J. X. Luu, D. C. Jewitt, M. Mutchler +4
The 4 km diameter main belt asteroid 6478 Gault has ejected dust intermittently since at least 2013. The character of the emission, including its episodic nature and the low…
'Oumuamua as a Cometary Fractal Aggregate: the "Dust Bunny" Model
J. X. Luu, E. G. Flekkøy, R. Toussaint
The first known interstellar object, 1I/2017 U1 'Oumuamua, displayed such unusual properties that its origin remains a subject of much debate. We propose that 'Oumuamua's propertie…
Initial Characterization of Interstellar Comet 2I/2019 Q4 (Borisov)
David Jewitt, Jane Luu
We present initial observations of the interstellar body 2I/(2019 Q4) Borisov taken to determine its nature prior to the perihelion in 2019 December. Images from the Nordic Optical…
The interstellar object 'Oumuamua as a fractal dust aggregate
Eirik G. Flekkøy, Jane X. Luu, Renaud Toussaint
The first known interstellar object 'Oumuamua exhibited a nongravitational acceleration that appeared inconsistent with cometary outgassing, leaving radiation pressure as the most…
