Asteroid modelling by starlight diffraction: The shape of Dimorphos, the satellite of (65803) Didymos
P. Tanga, K. Tsiganis, D. Souami +17
The DART spacecraft impacted Dimorphos, the satellite of (65803) Didymos, in September 2022. Evidence of crater formation and possible global reshaping has been obtained indirectly…
Shape and spin-state model of tumbling asteroid (319) Leona
J. Ďurech, J. L. Ortiz, M. Ferrais +14
Stellar occultations by asteroids observed from several stations are routinely used to reconstruct the asteroid's sky-plane projections. Together with the asteroid's shape model re…
Constraints on Triton atmospheric evolution from occultations: 1989-2022
B. Sicardy, A. Tej, A. R. Gomes-Junior +49
Context - Around the year 2000, Triton's south pole experienced an extreme summer solstice that occurs every about 650 years, when the subsolar latitude reached about 50°. Bracketi…
Secular change in the spin states of asteroids due to radiation and gravitation torques. New detections and updates of the YORP effect
J. Ďurech, D. Vokrouhlický, P. Pravec +21
The rotation state of small asteroids is affected in the long term by perturbing torques of gravitational and radiative origin (the YORP effect). Direct observational evidence of t…
The two rings of (50000) Quaoar
C. L. Pereira, B. Sicardy, B. E. Morgado +66
Quaoar is a classical Trans-Neptunian Object (TNO) with an area equivalent diameter of 1,100 km and an orbital semi-major axis of 43.3 astronomical units. Based on stellar occultat…
The equilibrium shape of (65) Cybele: primordial or relic of a large impact?
M. Marsset, M. Brož, J. Vermersch +24
Cybele asteroids constitute an appealing reservoir of primitive material genetically linked to the outer Solar System, and the physical properties of the largest members can be rea…
Observed tidal evolution of Kleopatra's outer satellite
M. Brož, J. Ďurech, B. Carry +8
The orbit of the outer satellite Alexhelios of (216) Kleopatra is already constrained by adaptive-optics astrometry, obtained with the VLT/SPHERE instrument. However, there is also…
Asteroid pairs: a complex picture
P. Pravec, P. Fatka, D. Vokrouhlický +45
We studied 93 asteroid pairs. We estimated times elapsed since separation of pair members that are between 7*10^3 and a few 10^6 yr. We derived the rotation periods for all the pri…
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…
Characteristics and Large Bulk Density of the C-type Main-Belt Triple Asteroid (93) Minerva
F. Marchis, F. Vachier, J. Ďurech +11
From a set of adaptive optics (AO) observations collected with the W.M. Keck telescope between August and September 2009, we derived the orbital parameters of the most recently dis…
Analysis of the rotation period of asteroids (1865) Cerberus, (2100) Ra-Shalom, and (3103) Eger - search for the YORP effect
J. Durech, D. Vokrouhlicky, A. R. Baransky +28
The spin state of small asteroids can change on a long timescale by the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect, the net torque that arises from anisotropically scatter…
The Origin of (90) Antiope From Component-Resolved Near-Infrared Spectroscopy
Franck Marchis, J. Emilio Enriquez, Joshua P. Emery +3
The origin of the similary-sized binary asteroid (90) Antiope remains an unsolved puzzle. To constrain the origin of this unique double system, we recorded individual spectra of th…
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…
