Detection of the YORP Effect for Small Asteroids in the Karin Cluster
TL;DR: In this paper, the authors used the Yarkovsky effect to estimate the spin obliquities of the Karin cluster members, and showed that the relative strength of the YORP effect is roughly the same as the nominal strength obtained for a collection of random Gaussian spheroids.

TL;DR: In this paper, the authors proposed a near-Earth object observations program for NASA's Near Earth Object Observations Program (NNX14AL06G), which is a part of the NASA Planetary Geology and Geophysics (PGG) program.

On the oldest asteroid families in the main belt
Valerio Carruba,Valerio Carruba,David Nesvorný,Safwan Aljbaae,R. C. Domingos,R. C. Domingos,M. Huaman +6 more
TL;DR: In this paper, the authors investigated the dynamical stability of seven of the allegedly oldest families in the asteroid main belt and showed that none of the seven studied families has a nominally mean estimated age older than 2.7 Gyr, assuming standard values for the parameters describing the strength of the Yarkovsky force.
Spin-driven evolution of asteroids’ top-shapes at fast and slow spins seen from (101955) Bennu and (162173) Ryugu

TL;DR: In this paper, a semi-analytical approach was applied to calculate the cohesive strength distribution in a uniformly rotating triaxial ellipsoid to characterize the global failure of top-shaped bodies.

Timing of thermal metamorphism in CM chondrites: Implications for Ryugu and Bennu future sample return
Elsa Amsellem,Frédéric Moynier,Frédéric Moynier,Brandon Mahan,Brandon Mahan,Pierre Beck,Pierre Beck +6 more
TL;DR: In this article, a dating system based on the radioactive decay of 87Rb to 87Sr (λ87Rb = 1.393 × 10−11−11yr−1) was used to date the heating event relating to the fractionation of Rb and Sr.

Rapid planetesimal formation in turbulent circumstellar disks
Anders Johansen,Jeffrey S. Oishi,Jeffrey S. Oishi,Mordecai-Mark Mac Low,Mordecai-Mark Mac Low,Hubert Klahr,Thomas Henning,Andrew N. Youdin +7 more
TL;DR: It is reported that boulders can undergo efficient gravitational collapse in locally overdense regions in the midplane of the disk, and it is found that gravitationally bound clusters form with masses comparable to dwarf planets and containing a distribution of boulder sizes.

A low mass for Mars from Jupiter's early gas―driven migration
Kevin J. Walsh,Alessandro Morbidelli,Sean N. Raymond,Sean N. Raymond,David P. O'Brien,Avi Mandell +5 more
TL;DR: Simulation of the early Solar System shows how the inward migration of Jupiter to 1.5 au, and its subsequent outward migration, lead to a planetesimal disk truncated at 1’au; the terrestrial planets then form from this disk over the next 30–50 million years, with an Earth/Mars mass ratio consistent with observations.

The Long-Term Dynamical Behavior of Short-Period Comets
TL;DR: In this paper, the authors developed and tested a new computer code to follow the long-term dynamical evolution of a swarm of test particles in the solar system and found that the Tisserand parameter, T, does not vary substantially for most comets.

Debiased Orbital and Absolute Magnitude Distribution of the Near-Earth Objects
William F. Bottke,Alessandro Morbidelli,Robert Jedicke,Jean-Marc Petit,Harold F. Levison,Patrick Michel,Travis S. Metcalfe +6 more
TL;DR: In this article, a best-fit model of the near-Earth objects (NEOs) population is presented, which is fit to known NEs discovered or accidentally rediscovered by Spacewatch.
The long-term dynamical behavior of short-period comets
TL;DR: In this article, it is shown that the anomalous concentration of the argument of perihelion of the Jupiter-family comets near 0 and 180 deg is a direct result of their aphelion distance being close to 5.2AU and the comet being recently perturbed onto a Jupiter- family orbit.
