The young Hobson family: Possible binary parent body and low-velocity dispersal
David Vokrouhlický, Miroslav Brož, Bojan Novaković +1
Asteroid families with ages younger than Myr offer an interesting possibility of studying the outcomes of asteroid disruptions that are little modified by subsequent evolutiona…
Can a jumping-Jupiter trigger the Moon's formation impact?
Sandro R. DeSouza, Fernando Roig, David Nesvorný
We investigate the possibility that the Moon's formation impact was triggered by an early dynamical instability of the giant planets. We consider the well-studied "jumping Jupiter"…
The young Adelaide family: Possible sibling to Datura?
D. Vokrouhlický, B. Novaković, D. Nesvorný
Very young asteroid families may record processes that accompanied their formation in the most pristine way. This makes analysis of this special class particularly interesting. We…
Astrocladistics of the Jovian Trojan Swarms
Timothy R. Holt, Jonathan Horner, David Nesvorný +4
The Jovian Trojans are two swarms of small objects that share Jupiter's orbit, clustered around the leading and trailing Lagrange points, L and L. In this work, we investig…
Migration of gap-opening planets in 3D stellar-irradiated accretion disks
Ondřej Chrenko, David Nesvorný
Context. The origin of giant planets at moderate separations au is still not fully understood because numerical studies of Type II migration in protoplanetary di…
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…
A super-Earth and a mini-Neptune around Kepler-59
X. Saad-Olivera, C. F. Martinez, A. Costa de Souza +2
We characterize the radii and masses of the star and planets in the Kepler-59 system, as well as their orbital parameters. The star parameters are determined through a standard spe…
Origin and evolution of long-period comets
David Vokrouhlický, David Nesvorný, Luke Dones
We develop an evolutionary model of the long-period comet (LPC) population, starting from their birthplace in a massive trans-Neptunian disk that was dispersed by migrating giant p…
A resonant pair of warm giant planets revealed by TESS
David Kipping, David Nesvorný, Joel Hartman +4
We present the discovery of a pair of transiting giant planets, TOI-216b and c, using four sectors of TESS photometry. TOI-216 is a dwarf orbited by two transiters…
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…
Secular Resonance Between Iapetus and the Giant Planets
Matija Ćuk, Luke Dones, David Nesvorný +1
Using numerical integrations, we find that the orbital eccentricity of Saturn's moon Iapetus undergoes prominent multi-Myr oscillations. We identify the responsible resonant argume…
Cladistical analysis of the Jovian and Saturnian satellite systems
Timothy. R. Holt, Adrian. J. Brown, David Nesvorný +2
Jupiter and Saturn each have complex systems of satellites and rings. These satellites can be classified into dynamical groups, implying similar formation scenarios. Recently, a la…
Detection of the Yarkovsky effect for C-type asteroids in the Veritas family
Valerio Carruba, David Vokrouhlický, David Nesvorný
The age of a young asteroid family can be determined by tracking the orbits of family members backward in time and showing that they converge at some time in the past. Here we cons…
Planetary Chaos and the (In)stability of Hungaria Asteroids
Matija Ćuk, David Nesvorný
The Hungaria asteroid group is located interior to the main asteroid belt, with semimajor axes between 1.8 and 2 AU, low eccentricities and inclinations of 16-35 degrees. Recently,…
Masses of Kepler-46b, c from Transit Timing Variations
Ximena Saad-Olivera, David Nesvorný, David M. Kipping +1
We use 16 quarters of the \textit{Kepler} mission data to analyze the transit timing variations (TTVs) of the extrasolar planet Kepler-46b (KOI-872). Our dynamical fits confirm tha…
Scattering V-type asteroids during the giant planets instability: A step for Jupiter, a leap for basalt
Pedro Brasil, Fernando Roig, David Nesvorný +1
V-type asteroids are a taxonomic class whose surface is associated to a basaltic composition. The only known source of V-type asteroids in the Main Asteroid Belt is (4) Vesta, that…
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…
Dynamical Evidence for a Late Formation of Saturn's Moons
Matija Ćuk, Luke Dones, David Nesvorný
We explore the past evolution of Saturn's moons using direct numerical integrations. We find that the past Tethys-Dione 3:2 orbital resonance predicted in standard models likely di…
Jumping Jupiter can explain Mercury's orbit
Fernando Roig, David Nesvorný, Sandro Ricardo DeSouza
The orbit of Mercury has large values of eccentricity and inclination that cannot be easily explained if this planet formed on a circular and coplanar orbit. Here, we study the evo…
On the oldest asteroid families in the main belt
V. Carruba, D. Nesvorný, S. Aljbaae +2
Asteroid families are groups of minor bodies produced by high-velocity collisions. After the initial dispersions of the parent bodies fragments, their orbits evolve because of seve…
Footprints of a possible Ceres asteroid paleo-family
V. Carruba, D. Nesvorný, S. Marchi +1
Ceres is the largest and most massive body in the asteroid main belt. Observational data from the Dawn spacecraft reveal the presence of at least two impact craters about 280~km in…
Characterizing the original ejection velocity field of the Koronis family
Valerio Carruba, David Nesvorný, Safwan Aljbaae
An asteroid family forms as a result of a collision between an impactor and a parent body. The fragments with ejection speeds higher than the escape velocity from the parent body c…
Constraints on the original ejection velocity fields of asteroid families
Valerio Carruba, David Nesvorný
Asteroid families form as a result of large-scale collisions among main belt asteroids. The orbital distribution of fragments after a family-forming impact could inform us about th…
The evolution of asteroids in the jumping-Jupiter migration model
Fernando Roig, David Nesvorný
In this work, we investigate the evolution of a primordial belt of asteroids, represented by a large number of massless test particles, under the gravitational effect of migrating…
