Asteroid sizes determined with thermophysical model and stellar occultations

A. Choukroun, A. Marciniak, J. Ďurech +165

Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…

Scaling slowly rotating asteroids by stellar occultations

A. Marciniak, J. Ďurech, A. Choukroun +176

As evidenced by recent survey results, majority of asteroids are slow rotators (P>12 h), but lack spin and shape models due to selection bias. This bias is skewing our overall unde…

Properties of slowly rotating asteroids from the Convex Inversion Thermophysical Model

A. Marciniak, J. Ďurech, V. Alí-Lagoa +73

Results from the TESS mission showed that previous studies strngly underestimated the number of slow rotators, revealing the importance of studying those asteroids. For most slowly…

(216) Kleopatra, a low density critically rotating M-type asteroid

F. Marchis, L. Jorda, P. Vernazza +36

Context. The recent estimates of the 3D shape of the M/Xe-type triple asteroid system (216) Kleopatra indicated a density of 5 g.cm. Such a high density implies a high metal…

An advanced multipole model for (216) Kleopatra triple system

M. Brož, F. Marchis, L. Jorda +37

To interpret adaptive-optics observations of (216) Kleopatra, we need to describe an evolution of multiple moons, orbiting an extremely irregular body and including their mutual in…

Thermal properties of slowly rotating asteroids: Results from a targeted survey

A. Marciniak, V. Alí-Lagoa, T. G. Müller +51

Context. Earlier work suggests that slowly rotating asteroids should have higher thermal inertias than faster rotators because the heat wave penetrates deeper into the sub-surface.…

The homogeneous internal structure of CM-like asteroid (41) Daphne

B. Carry, F. Vachier, J. Berthier +48

Context. CM-like asteroids (Ch and Cgh classes) are a major population within the broader C-complex, encompassing about 10% of the mass of the main asteroid belt. Their internal st…

Physical, spectral, and dynamical properties of asteroid (107) Camilla and its satellites

M. Pajuelo, B. Carry, F. Vachier +24

The population of large asteroids is thought to be primordial and they are the most direct witnesses of the early history of our Solar System. Those satellites allow study of the m…

Against the biases in spins and shapes of asteroids

A. Marciniak, F. Pilcher, D. Oszkiewicz +21

Physical studies of asteroids depend on an availability of lightcurve data. Targets that are easy to observe and analyse naturally have more data available, so their synodic period…

Photometric survey, modelling, and scaling of long-period and low-amplitude asteroids

A. Marciniak, P. Bartczak, T. Müller +40

The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes. As a consequence of these select…

New and updated convex shape models of asteroids based on optical data from a large collaboration network

J. Hanuš, J. Ďurech, D. A. Oszkiewicz +165

Asteroid modeling efforts in the last decade resulted in a comprehensive dataset of almost 400 convex shape models and their rotation states. This amount already provided a deep in…

The small binary asteroid (939) Isberga

B. Carry, A. Matter, P. Scheirich +29

In understanding the composition and internal structure of asteroids, their density is perhaps the most diagnostic quantity. We aim here to characterize the surface composition, mu…

Asteroids' physical models from combined dense and sparse photometry and scaling of the YORP effect by the observed obliquity distribution

J. Hanuš, J. Ďurech, M. Brož +116

The larger number of models of asteroid shapes and their rotational states derived by the lightcurve inversion give us better insight into both the nature of individual objects and…

Spectroscopy of BL Cam - Observations

M. Alvarez, R. Michel, L. Fox-Machado +3

The star BL Camelopardalis (GD 428, GSC 04067-00471, V=12.92, B=13.1), is a SX Phoenicis pulsating variable showing a high amplitude variability (300-350 mmag), with a very clear p…

The field high-amplitude SX Phe variable BL Cam: results from a multisite photometric campaign. II. Evidence of a binary - possibly triple - system

S. Fauvaud, J. -P. Sareyan, I. Ribas +45

Short-period high-amplitude pulsating stars of Population I ( Sct stars) and II (SX Phe variables) exist in the lower part of the classical (Cepheid) instability strip. Most of…

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…
