Shape and spin state model of contact binary (388188) 2006 DP14 using combined radar and optical observations

Richard E. Cannon, Agata Rozek, Marina Brozović +36

Contact binaries are found throughout the solar system. The recent discovery of Selam, the satellite of MBA (152830) Dinkinesh, by the NASA LUCY mission has made it clear that the…

Predictions for Sparse Photometry of Jupiter-Family Comet Nuclei in the LSST Era

A. Donaldson, C. Snodgrass, R. Kokotanekova +1

The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory will deliver high-quality, temporally-sparse observations of millions of Solar System objects on an unpreced…

Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks

Theodore Kareta, Cristina Thomas, Jian-Yang Li +85

The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…

Orbital Period Change of Dimorphos Due to the DART Kinetic Impact

Cristina A. Thomas, Shantanu P. Naidu, Peter Scheirich +46

The Double Asteroid Redirection Test (DART) spacecraft successfully performed the first test of a kinetic impactor for asteroid deflection by impacting Dimorphos, the secondary of…

Physical properties of near-Earth asteroid (2102) Tantalus from multi-wavelength observations

Agata Rożek, Stephen C. Lowry, Benjamin Rozitis +20

Between 2010 and 2017 we have collected new optical and radar observations of the potentially hazardous asteroid (2102)~Tantalus from the ESO NTT and Danish telescopes at the La Si…

Detection of the YORP Effect on the contact-binary (68346) 2001 KZ66 from combined radar and optical observations

Tarik J. Zegmott, S. C. Lowry, A. Rożek +7

The YORP effect is a small thermal-radiation torque experienced by small asteroids, and is considered to be crucial in their physical and dynamical evolution. It is important to un…

Observations and analysis of a curved jet in the coma of comet 67P/Churyumov-Gerasimenko

Zhong-Yi Lin, I. -L. Lai, C. -C. Su +48

We analyze the physical properties and dynamical origin of a curved jet of comet 67P/Churyumov-Gerasimenko that was observed repeatedly in several nucleus rotations starting on May…

Distant activity of 67P/Churyumov-Gerasimenko in 2014: Ground-based results during the Rosetta pre-landing phase

Colin Snodgrass, Emmanuel Jehin, Jean Manfroid +14

As the ESA Rosetta mission approached, orbited, and sent a lander to comet 67P/Churyumov-Gerasimenko in 2014, a large campaign of ground-based observations also followed the comet.…

Stress field and spin axis relaxation for inelastic triaxial ellipsoids

Slawomir Breiter, Agata Rozek, David Vokrouhlicky

A compact formula for the stress tensor inside a self-gravitating, triaxial ellipsoid in an arbitrary rotation state is given. It contains no singularity in the incompressible medi…

Absolute properties of the main-sequence eclipsing binary FM Leo

M. Ratajczak, T. Kwiatkowski, A. Schwarzenberg-Czerny +9

First spectroscopic and new photometric observations of the eclipsing binary FM Leo are presented. The main aims were to determine orbital and stellar parameters of two components…

Asteroseismology of hybrid pulsators made possible: simultaneous MOST space photometry and ground-based spectroscopy of Gamma Peg

G. Handler

We have acquired simultaneous high-precision space photometry and radial velocities of the bright hybrid Beta Cep/SPB pulsator Gamma Peg. Frequency analyses reveal the presence of…

V440 Per: the longest period overtone Cepheid

R. Baranowski, R. Smolec, W. Dimitrov +9

V440 Per is a Population I Cepheid with the period of 7.57 day and low amplitude, almost sinusoidal light and radial velocity curves. With no reliable data on the 1st harmonic, its…
