Tracing the main belt origins of S-complex near-Earth objects: From space mission targets to meteorite sources
P. N. Simon, P. Vernazza, M. Marsset +5
Context. Space missions to near-Earth objects (NEOs) provide unique opportunities to study and characterise their physical and compositional properties. Interpreting these results…
Shaken, not stirred: inefficient mixing of CM- and CI-like materials
Sarah E. Anderson, Pierre Vernazza, Miroslav Broz
A recent study suggests that CM chondrite-like planetesimals formed in the vicinity of Saturn, in a pressure bump outside the gap carved by proto-Jupiter. While a fraction of these…
The Nysa family as the main source of unequilibrated LL ordinary chondrites
M. Marsset, P. Vernazza, M. Brož +16
Context. The origin of the petrologic diversity observed in ordinary chondrites (OCs), the most common meteorites on Earth, remains debated. Competing models invoke either depth-de…
Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
Source regions of carbonaceous meteorites and NEOs
M. Brož, P. Vernazza, M. Marsset +15
The present work aims to determine the source regions of carbonaceous chondrites (CM, CI, CO, CV, CK, CR, CH, CB, or C-ungrouped). We studied 38 individual asteroid families, inclu…
The Massalia asteroid family as the origin of ordinary L chondrites
Michaël Marsset, Pierre Vernazza, Miroslav Brož +10
Studies of micrometeorites in mid-Ordovician limestones and Earth's impact craters indicate that our planet witnessed a massive infall of ordinary L chondrite material 466 million…
An advanced multipole model of the (130) Elektra quadruple system
M. Fuksa, M. Brož, J. Hanuš +3
The Ch-type asteroid (130) Elektra is orbited by three moons, making it the first quadruple system in the main asteroid belt. We aim to characterise the irregular shape of Elektra…
Discovery of an asteroid family linked to (22) Kalliope and its moon Linus
M. Brož, M. Ferrais, P. Vernazza +2
According to adaptive-optics observations by Ferrais et al., (22) Kalliope is a 150-km, dense and differentiated body. Here, we interpret (22) Kalliope in the context of bodies in…
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…
Physical and dynamical characterization of the Euphrosyne asteroid Family
B. Yang, J. Hanus, M. Broz +5
The Euphrosyne asteroid family occupies a unique zone in orbital element space around 3.15 au and may be an important source of the low-albedo near-Earth objects. The parent body o…
Binary asteroid (31) Euphrosyne: Ice-rich and nearly spherical
B. Yang, J. Hanus, B. Carry +38
Asteroid (31) Euphrosyne is one of the biggest objects in the asteroid main belt and the Euphrosyne family occupies a highly inclined region in the outer main belt and contains a r…
Impacts into rotating targets: angular momentum draining and efficient formation of synthetic families
P. Ševeček, M. Brož, M. Jutzi
About 10% of the observed asteroids have rotational periods lower than P = 3 h and they seem to be relatively close to the spin barrier. Yet, the rotation has often been neglected…
The shape of (7) Iris as evidence of an ancient large impact?
J. Hanuš, M. Marsset, P. Vernazza +35
Asteroid (7) Iris is an ideal target for disk-resolved imaging owing to its brightness (V7-8) and large angular size of 0.33 arcsec during its apparitions. Iris is believed t…
The thermal emission from boulders on (25143) Itokawa and general implications for the YORP effect
P. Ševeček, M. Brož, D. Čapek +1
Infrared radiation emitted from an asteroid surface causes a torque that can significantly affect rotational state of the asteroid. The influence of small topographic features on t…
A study of asteroid pole-latitude distribution based on an extended set of shape models derived by the lightcurve inversion method
Josef Hanus, Josef Durech, Miroslav Broz +12
Tens of thousands of sparse-in-time lightcurves from astrometric projects are publicly available. We investigate these data and use them in the lightcurve inversion method to deriv…
