Discovery of 63 New Young Asteroid Families
David Nesvorny, David Vokrouhlicky, Miroslav Broz +1
We searched for young asteroid families -- those with ages t_age < 10 Myr and at least three members -- using the proper element catalog from Nesvorny et al. (2024). Our approach e…
Multi-scale radiative-transfer model of the protoplanetary disc DoAr 44
Marco Souza de Joode, Miroslav Brož
We aim to construct a comprehensive global multi-scale kinematic equilibrium radiative-transfer model for the pre-transitional disc of DoAr 44 (Haro 1-16, V2062 Oph) in the Ophiuch…
Orbital and absolute magnitude distribution of Hilda population
David Vokrouhlický, David Nesvorný, Miroslav Brož +4
The Hilda population of asteroids is located in a large orbital zone of long-term stability associated with the Jupiter J3/2 mean motion resonance. They are a sister population of…
JWST sighting of decameter main-belt asteroids and view on meteorite sources
Artem Y. Burdanov, Julien de Wit, Miroslav Brož +19
Asteroid discoveries are essential for planetary-defense efforts aiming to prevent impacts with Earth, including the more frequent megaton explosions from decameter impactors. Whil…
Catalog of Proper Orbits for 1.25 Million Main Belt Asteroids and Discovery of 136 New Collisional Families
David Nesvorny, Fernando Roig, David Vokrouhlicky +1
The proper elements of asteroids are obtained from the instantaneous orbital elements by removing periodic oscillations produced by gravitational interactions with planets. They ar…
Young asteroid families as the primary source of meteorites
M. Brož, P. Vernazza, M. Marsset +4
Understanding the origin of bright shooting stars and their meteorite samples is among the most ancient astronomy-related questions that at larger scales has human consequences [1-…
Orbital and absolute magnitude distribution of Jupiter Trojans
David Vokrouhlický, David Nesvorný, Miroslav Brož +4
Jupiter Trojans (JTs) librate about the Lagrangian stationary centers L4 and L5 associated with this planet on a typically small-eccentricity and moderate-inclination heliocentric…
Debiased population of very young asteroid families
David Vokrouhlický, David Nesvorný, Miroslav Brož +1
We use observations from the Catalina Sky Survey (CSS) to determine the bias-corrected population of small members in four very young families down to sizes equivalent to several h…
NEOMOD: A New Orbital Distribution Model for Near Earth Objects
David Nesvorny, Rogerio Deienno, William F. Bottke +10
Near Earth Objects (NEOs) are a transient population of small bodies with orbits near or in the terrestrial planet region. They represent a mid-stage in the dynamical cycle of aste…
Terrestrial planet formation by torque-driven convergent migration of planetary embryos
M. Brož, O. Chrenko, D. Nesvorný +1
Massive cores of the giant planets are thought to have formed in a gas disk by accretion of pebble-size particles whose accretional cross-section is enhanced by aerodynamic gas dra…
Optically thin circumstellar medium in Lyr A system
M. Brož, D. Mourard, J. Budaj +7
beta Lyr A is a complex binary system with an extensive observational dataset: light curves (from FUV to FIR), interferometric squared visibility, closure phase, triple product mea…
A pair of Jovian Trojans at the L4 Lagrange point
Timothy R. Holt, David Vokrouhlický, David Nesvorný +2
Asteroid pairs, two objects that are not gravitationally bound to one another, but share a common origin, have been discovered in the Main belt and Hungaria populations. Such pairs…
Binary planet formation by gas-assisted encounters of planetary embryos
Ondřej Chrenko, Miroslav Brož, David Nesvorný
We present radiation hydrodynamic simulations in which binary planets form by close encounters in a system of several super-Earth embryos. The embryos are embedded in a protoplanet…
Dynamics of multiple protoplanets embedded in gas/pebble disks and its dependence on and parameters
Miroslav Brož, Ondřej Chrenko, David Nesvorný +1
Protoplanets of Super-Earth sizes may get trapped in convergence zones for planetary migration and form gas giants there. These growing planets undergo accretion heating, which tri…
SPH/N-body simulations of small (D = 10 km) asteroidal breakups and improved parametric relations for Monte-Carlo collisional models
P. Ševeček, M. Brož, D. Nesvorný +4
We report on our study of asteroidal breakups, i.e. fragmentations of targets, subsequent gravitational reaccumulation and formation of small asteroid families. We focused on paren…
Hektor - an exceptional D-type family among Jovian Trojans
Jakub Rozehnal, Miroslav Brož, David Nesvorný +4
In this work, we analyze Jovian Trojans in the space of suitable resonant elements and we identify clusters of possible collisional origin by two independent methods: the hierarchi…
Identification and Dynamical Properties of Asteroid Families
D. Nesvorny, M. Broz, V. Carruba
Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large a…
A six-part collisional model of the main asteroid belt
Helena Cibulková, Miroslav Brož, Paula G. Benavidez
In this work, we construct a new model for the collisional evolution of the main asteroid belt. Our goals are to test the scaling law of Benz and Asphaug (1999) and ascertain if it…
An anisotropic distribution of spin vectors in asteroid families
J. Hanuš, M. Brož, J. Ďurech +11
Current amount of ~500 asteroid models derived from the disk-integrated photometry by the lightcurve inversion method allows us to study not only the spin-vector properties of the…
Did the Hilda collisional family form during the late heavy bombardment?
M. Brož, D. Vokrouhlický, A. Morbidelli +2
We model the long-term evolution of the Hilda collisional family located in the 3/2 mean-motion resonance with Jupiter. Its eccentricity distribution evolves mostly due to the Yark…
Eurybates - the only asteroid family among Trojans?
Miroslav Brož, Jakub Rozehnal
We study orbital and physical properties of Trojan asteroids of Jupiter. We try to discern all families previously discussed in literature, but we conclude there is only one signif…
A unified solution for the orbit and light-time effect in the V505 Sgr system
M. Broz, P. Mayer, T. Pribulla +3
The multiple system V505 Sagittarii is composed of at least three stars: a compact eclipsing pair and a distant component, which orbit is measured directly using speckle interferom…
