Scaling slowly rotating asteroids with stellar occultations [PDF]
Astronomy & Astrophysics, 2023 Context. As evidenced by recent survey results, the majority of asteroids are slow rotators (spin periods longer than 12 h), but lack spin and shape models because of selection bias. This bias is skewing our overall understanding of the spins, shapes, and sizes of asteroids, as well as of their other properties. Also, diameter determinations for large (

ROTATIONAL PROPERTIES OF THE MARIA ASTEROID FAMILY [PDF]
The Astronomical Journal, 2014 Maria family is regarded as an old-type (~3 +/- 1 Gyr) asteroid family which has experienced substantial collisional and dynamical evolution in the Main-belt. It is located nearby the 3:1 Jupter mean motion resonance area that supplies Near-Earth asteroids (NEAs) to the inner Solar System.

Asteroid Photometric Phase Functions From Bayesian Lightcurve Inversion
Frontiers in Astronomy and Space Sciences, 2022 Photometry is an important tool for characterizing the physical properties of asteroids. An asteroid’s photometric lightcurve and phase curve refer to the variation of the asteroid’s disk-integrated brightness in time and in phase angle (the Sun-asteroid-

Limiting behavior of asteroid obliquity and spin using a semi-analytic thermal model of the YORP effect [PDF]
, 2021 The Yarkovsky--O'Keefe--Radzievskii--Paddack (YORP) effect governs the spin evolution of small asteroids. The axial component of YORP, which alters the rotation rate of the asteroid, is mostly independent of its thermal inertia, while the obliquity component is very sensitive to the thermal model of the asteroid.

Discovery of Super-Slow Rotating Asteroids with ATLAS and ZTF photometry [PDF]
, 2021 We present here the discovery of a new class of super-slow rotating asteroids (P>1000 hours) in data extracted from the Asteroid Terrestrial-impact Last Alert System (ATLAS) and Zwicky Transient Facility (ZTF) all-sky surveys. Of the 39 rotation periods we report here, 32 have periods longer than any previously reported unambiguous rotation periods ...

The Alinement of Asteroid Rotation [PDF]
International Astronomical Union Colloquium, 1971 Data have been accumulating since the beginning of this century that indicate that most, if not all, large asteroids have periodic lightcurves. The variations that are seen have periods of the order of several hours and can be understood as being caused by bodily rotation, accompanied by changes in shape and/or surface properties. Because corresponding

Photometry and shape modeling of Mars crosser asteroid (1011) Laodamia [PDF]
Serbian Astronomical Journal, 2014 An analysis of photometric observations of Mars crosser asteroid 1011 Laodamia conducted at Bulgarian National Astronomical Observatory Rozhen over a twelve year interval (2002, 2003, 2004, 2006, 2007, 2008, 2011, 2012 and 2013) is made.

Orbital Mechanics near a Rotating Asteroid [PDF]
Journal of Astrophysics and Astronomy, 2014 This study investigates the different novel forms of the dynamical equations of a particle orbiting a rotating asteroid and the effective potential, the Jacobi integral, etc. on different manifolds. Nine new forms of the dynamical equations of a particle orbiting a rotating asteroid are presented, and the classical form of the dynamical equations has ...
