Physical properties of ESA Rosetta target asteroid (21) Lutetia: Shape and flyby geometry
B. Carry, M. Kaasalainen, C. Leyrat +22
Aims. We determine the physical properties (spin state and shape) of asteroid (21) Lutetia, target of the ESA Rosetta mission, to help in preparing for observations during the flyb…
New determination of the size and bulk density of the binary asteroid 22 Kalliope from observations of mutual eclipses
P. Descamps, F. Marchis, J. Pollock +16
In 2007, the M-type binary asteroid 22 Kalliope reached one of its annual equinoxes. As a consequence, the orbit plane of its small moon, Linus, was aligned closely to the Sun's li…
The non-convex shape of (234) Barbara, the first Barbarian
P. Tanga, B. Carry, F. Colas +37
Asteroid (234) Barbara is the prototype of a category of asteroids that has been shown to be extremely rich in refractory inclusions, the oldest material ever found in the Solar Sy…
Triplicity and Physical Characteristics of Asteroid (216) Kleopatra
Pascal Descamps, F. Marchis, J. Berthier +16
To take full advantage of the September 2008 opposition passage of the M-type asteroid (216) Kleopatra, we have used near-infrared adaptive optics (AO) imaging with the W.M. Keck I…
The multi-faceted Type II-L supernova 2014G from pre-maximum to nebular phase
G. Terreran, A. Jerkstrand, S. Benetti +18
We present multi-band ultraviolet, optical, and near-infrared photometry, along with visual-wavelength spectroscopy, of supernova (SN) 2014G in the nearby galaxy NGC 3448 (25 Mpc).…
How low can you go? SN 2018zd as a low-mass Fe core-collapse supernova
E. Callis, M. Fraser, A. Pastorello +38
We present spectroscopy and photometry of SN 2018zd, a Type IIP core-collapse supernova with signatures of interaction with circumstantial material in its earliest spectra. High io…
A Giant Crater on 90 Antiope?
P. Descamps, F. Marchis, T. Michalowski +11
Mutual event observations between the two components of 90 Antiope were carried out in 2007-2008. The pole position was refined to lambda0 = 199.5+/-0.5 eg and beta0 = 39.8+/-5 deg…
