The Astronomical Journal, 2011 Some asteroids eject dust, unexpectedly producing transient, comet-like comae and tails. First ascribed to the sublimation of near-surface water ice, mass-losing asteroids (also called “main-belt comets”) can in fact be driven by a surprising diversity ...

Asteroid Family Associations of Active Asteroids [PDF]
The Astronomical Journal, 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 ...

Mineralogy and Surface Composition of Asteroids [PDF]
, 2015 Methods to constrain the surface mineralogy of asteroids have seen considerable development during the last decade with advancement in laboratory spectral calibrations and validation of our interpretive methodologies by spacecraft rendezvous missions ...

Rudarsko-geološko-naftni Zbornik, 2016 Asteroids are the largest minor bodies in the Solar System. Nowadays they are in the research focus due to several facts about them: first, a subclass of asteroids can collide with Earth, and consequences of such a collision are dramatic.

Dynamical Masses of 20 Asteroids Determined with Gaia DR3 Asteroid Observations
The Astronomical Journal, 2023 We combined the ground-based and Gaia Data Release 3 (DR3) asteroid observations to determine the masses of 20 asteroids with asteroid–asteroid close encounters.

Gravity-Assist might be a Solution to Save Earth from Global Warming [PDF]
Iranian Journal of Astronomy and Astrophysics, 2023 Global warming is one of the problems of human civilization and decarbonization policy is the main solution to this problem. In this work, we propose an alternative method of using the gravity assist by the asteroids to increase the orbital distance of ...

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.

Rotation Periods of Asteroids Determined With Bootstrap Convex Inversion From ATLAS Photometry
Frontiers in Astronomy and Space Sciences, 2022 The rotation period is one of the fundamental physical characteristics of asteroids. It can be determined from photometric measurements by standard methods of time-series period analysis or by creating a physical model of an asteroid with the rotation ...
