(3200) Phaethon: Bulk density from Yarkovsky drift detection
Josef Hanus, David Vokrouhlicky, Marco Delbo +8
The recent close approach of the NEA (3200) Phaethon offered a rare opportunity to obtain high-quality observational data. We used the newly obtained optical light curves to improv…
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…
Rotationally-Resolved Spectroscopic Characterization of near-Earth object (3200) Phaethon
Theodore Kareta, Vishnu Reddy, Carl Hergenrother +5
(3200) Phaethon is a compelling object as it has an asteroidal appearance and spectrum, produces a weak dust tail during perihelion at just 0.14 AU, and is the parent body of the G…
Reconstruction of asteroid spin states from Gaia DR2 photometry
Josef Durech, Josef Hanus
In addition to stellar data, Gaia Data Release 2 (DR2) also contains accurate astrometry and photometry of about 14,000 asteroids covering 22 months of observations. We used Gaia a…
A study of 3-dimensional shapes of asteroid families with an application to Eos
Miroslav Brož, Alessandro Morbidelli
In order to fully understand the shapes of asteroids families in the 3-dimensional space of the proper elements it is necessary to compare…
(16) Psyche: A mesosiderite-like asteroid?
M. Viikinkoski, P. Vernazza, J. Hanus +35
Asteroid (16) Psyche is the target of the NASA Psyche mission. It is considered one of the few main-belt bodies that could be an exposed proto-planetary metallic core and that woul…
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…
Evidence for Very Early Migration of the Solar System Planets from the Patroclus-Menoetius binary Jupiter Trojan
David Nesvorny, David Vokrouhlicky, William F. Bottke +1
The orbital distribution of trans-Neptunian objects provides strong evidence for the radial migration of Neptune. The outer planets' orbits are thought to have become unstable duri…
Asteroid models reconstructed from the Lowell Photometric Database and WISE data
Josef Durech, Josef Hanus, Victor Ali-Lagoa
Information about the spin state of asteroids is important for our understanding of the dynamical processes affecting them. However, spin properties of asteroids are known for only…
Debiased orbit and absolute-magnitude distributions for near-Earth objects
Mikael Granvik, Alessandro Morbidelli, Robert Jedicke +6
The debiased absolute-magnitude and orbit distributions as well as source regions for near-Earth objects (NEOs) provide a fundamental frame of reference for studies of individual N…
Gaia Data Release 2: Observations of solar system objects
Gaia Collaboration, F. Spoto, P. Tanga +4
The Gaia spacecraft of the European Space Agency (ESA) has been securing observations of solar system objects (SSOs) since the beginning of its operations. Gaia Data Release 2 (DR2…
Bi-lobed Shape of Comet 67P from a Collapsed Binary
David Nesvorny, Joel Parker, David Vokrouhlicky
The Rosetta spacecraft observations revealed that the nucleus of comet 67P/Churyumov-Gerasimenko consists of two similarly sized lobes connected by a narrow neck. Here we evaluate…
Asteroid families interacting with secular resonances
V. Carruba, D. Vokrouhlický, B. Novakovic
Asteroid families are formed as the result of collisions. Large fragments are ejected with speeds of the order of the escape velocity from the parent body. After the family formati…
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…
On the age of the Nele asteroid family
V. Carruba, D. Vokrouhlický, D. +2
The Nele group, formerly known as the Iannini family, is one of the youngest asteroid families in the main belt. Previously, it has been noted that the pericenter longitudes $\varp…
The random walk of cars and their collision probabilities with planets
Hanno Rein, Daniel Tamayo, David Vokrouhlicky
On February 6th, 2018 SpaceX launched a Tesla Roadster on a Mars-crossing orbit. We perform N-body simulations to determine the fate of the object over the next 15 Myr. The orbital…
Thermophysical modeling of main-belt asteroids from WISE thermal data
Josef Hanus, Marco Delbo, Josef Durech +1
By means of a varied-shape thermophysical model (VS-TPM) of Hanus et al. (2015) that takes into account asteroid shape and pole uncertainties, we analyze the thermal IR data acquir…
