Orbits of the Asteroids Discovered at the Molėtai Observatory in 2000–2004

open access: yesOpen 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.

Small Near-Earth Asteroids as a Source of Meteorites [PDF]

open access: yes, 2015
Small asteroids intersecting Earth's orbit can deliver extraterrestrial rocks to the Earth, called meteorites. This process is accompanied by a luminous phenomena in the atmosphere, called bolides or fireballs.

New and updated convex shape models of asteroids based on optical data from a large collaboration network [PDF]

open access: yes, 2015
Context. Asteroid modeling efforts in the last decade resulted in a comprehensive dataset of almost 400 convex shape models and their rotation states. These efforts already provided deep insight into physical properties of main-belt asteroids or large ...

V-type Asteroids as the Origin of Mesosiderites

open access: yesThe Planetary Science Journal, 2023
We present the results of a campaign of hypervelocity impact experiments on natural mesosiderite targets, using representative main asteroid belt impact speeds. The objective is to document further the surface evolution of iron-rich asteroids.

Formation and Evolution of Binary Asteroids [PDF]

open access: yes, 2015
Satellites of asteroids have been discovered in nearly every known small body population, and a remarkable aspect of the known satellites is the diversity of their properties.

Asteroid Spin-Rate Study using the Intermediate Palomar Transient Factory [PDF]

open access: yes, 2015
Two dedicated asteroid rotation-period surveys have been carried out using data taken on January 6-9 and February 20-23 of 2014 by the Intermediate Palomar Transient Factory (iPTF) in the $R$~band with $\sim 20$-min cadence. The total survey area covered

The Solar System Notification Alert Processing System (SNAPS): Design, Architecture, and First Data Release (SNAPShot1)

open access: yesThe Astronomical Journal, 2023
We present here the design, architecture, and first data release for the Solar System Notification Alert Processing System (SNAPS). SNAPS is a solar system broker that ingests alert data from all-sky surveys.
