A Spectroscopic Comparison of HED Meteorites and V-type Asteroids in the Inner Main Belt [PDF]
, 2010 V-type asteroids in the inner Main Belt (a < 2.5 AU) and the HED meteorites are thought to be genetically related to one another as collisional fragments from the surface of the large basaltic asteroid 4 Vesta.

Astronomical Observations of Volatiles on Asteroids [PDF]
, 2015 We have long known that water and hydroxyl are important components in meteorites and asteroids. However, in the time since the publication of Asteroids III, evolution of astronomical instrumentation, laboratory capabilities, and theoretical models have ...

Collision and annihilation of relative equilibrium points around asteroids with a changing parameter [PDF]
, 2015 In this work, we investigate the bifurcations of relative equilibria in the gravitational potential of asteroids. A theorem concerning a conserved quantity, which is about the eigenvalues and number of relative equilibria, is presented and proved.

Near-Earth Asteroids as Possible Parent Bodies of Meteor Streams [PDF]
Учёные записки Казанского университета: Серия Естественные науки, 2016 The genetic relationship of meteor streams with near-Earth asteroids (NEAs) is being actively studied. A genetic link with the asteroid is possible only for streams in which meteoroids have the geocentric speed smaller than 50 km/s, thereby meaning the ...

ASTEROIDS EXPLORATION WITH BALDONE SCHMIDT TELE-SCOPE
Odessa Astronomical Publications, 2018 CCD observations of asteroids were ob-tained in 2008 with the Baldone Schmidt telescope (aper-ture/diameter/focal length = 80/120/240 cm) at the Bal-done Astrophysical observatory (code 069) of the Institute of Astronomy of the University of Latvia.

Third derivatives of the integrable part of an asteroid Hamiltonian [PDF]
Serbian Astronomical Journal, 2007 To apply the theorem of Nekhoroshev (1977) to asteroids, one first has to check whether a necessary geometrical condition is fulfilled: either convexity, or quasi-convexity, or only a 3-jet non-degeneracy.

Dynamics of Polar Resonances and Their Effects on Kozai–Lidov Mechanism
Applied Sciences, 2022 The research on highly inclined mean motion resonances (MMRs), even retrograde resonances, has drawn more attention in recent years. However, the dynamics of polar resonance with inclination i≈90∘ have received much less attention.

BVRI photometry of 53 unusual asteroids
, 2010 We present the results of BVRI photometry and classification of 53 unusual asteroids, including 35 near-Earth asteroids (NEAs), 6 high eccentricity/inclination asteroids, and 12 recently-identified asteroid-pair candidates.

Trajectory Design Employing Convex Optimization for Landing on Irregularly Shaped Asteroids
Journal of Guidance Control and Dynamics, 2016 The problem under investigation is how to rapidly design a propellant optimal powered descent trajectory to land a spacecraft on an arbitrarily shaped asteroid, subject to realistic constraints on ...
