The common origin of family and non-family asteroids [PDF]
Nature Astronomy, 2018 All asteroids are currently classified as either family, originating from the disruption of known bodies1, or non-family. An outstanding question is the origin of these non-family asteroids.

SAFARI: Searching Asteroids for Activity Revealing Indicators [PDF]
Publications of the Astronomical Society of the Pacific, 2018 Active asteroids behave dynamically like asteroids but display comet-like comae. These objects are poorly understood, with only about 30 identified to date.

Asteroid Family Associations of Active Asteroids [PDF]
, 2018 We report on the results of a systematic search for associated asteroid families for all active asteroids known to date. We find that 10 out of 12 main-belt comets (MBCs) and five out of seven disrupted asteroids are linked with known or candidate ...

Interpreting the Cratering Histories of Bennu, Ryugu, and Other Spacecraft-explored Asteroids
Astronomical Journal, 2019 Asteroid crater retention ages have unknown accuracy because projectile–crater scaling laws are difficult to verify. At the same time, our knowledge of asteroid and crater size–frequency distributions has increased substantially over the past few decades.

Orbits of the Asteroids Discovered at the Molėtai Observatory in 2000–2004
Open Astronomy, 2014 The paper presents statistics of the asteroids observed and discovered at the Molėtai Observatory, Lithuania in 2000–2004 within the project for astrometric observations of the near-Earth objects (NEOs), the main belt asteroids and comets.

NEOWISE Reactivation Mission Year One: Preliminary Asteroid Diameters and Albedos [PDF]
, 2015 We present preliminary diameters and albedos for 7,959 asteroids detected in the first year of the NEOWISE Reactivation mission. 201 are near-Earth asteroids (NEAs). 7,758 are Main Belt or Mars-crossing asteroids.

The 3 $\mu$m Spectrum of Jupiter's Irregular Satellite Himalia [PDF]
, 2014 We present a medium resolution spectrum of Jupiter's irregular satellite Himalia covering the critical 3 $\mu$m spectral region. The spectrum shows no evidence for aqueously altered phyllosilicates, as had been suggested from the tentative detection of a

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Inelastic Dissipation in Wobbling Asteroids and Comets [PDF]
, 1998 Asteroids and comets dissipate energy when they rotate about the axis different from the axis of the maximal moment of inertia. We show that the most efficient internal relaxation happens at the double frequency of body's tumbling.
