Constraining planet formation around 6M⊙-8M⊙ stars [PDF]
, 2020 Identifying planets around O-type and B-type stars is inherently difficult; the most massive known planet host has a mass of only about 3M⊙. However, planetary systems which survive the transformation of their host stars into white dwarfs can be detected

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.

Thermal Model Calibration for Minor Planets Observed with Wide-Field Infrared Survey Explorer/Neowise [PDF]
, 2011 With the Wide-field Infrared Survey Explorer (WISE), we have observed over 157,000 minor planets. Included in these are a number of near-Earth objects, main-belt asteroids, and irregular satellites which have well measured physical properties (via radar ...

Observational Data and Orbits of the Asteroids Discovered at the Baldone Observatory in 2008–2013
Open Astronomy, 2015 The paper presents statistics of the asteroids observed and discovered at the Baldone Observatory, Latvia, in 2008–2013 within the project for astrometric observations of the near-Earth objects (NEOs), the main belt asteroids and comets. CCD observations

Interaction between Yarkovsky force and mean-motion resonances: Some specific properties [PDF]
Serbian Astronomical Journal, 2016 Recently, we analyzed the role of mean-motion resonances in semi-major axis mobility of asteroids, and established a functional relationship that describes the dependence of the average time spent inside the resonance on the strength of this ...

CCD photometry and new models of 5 minor planets [PDF]
, 1999 We present new R filtered CCD observations of 5 faint and moderately faint asteroids carried out between October, 1998 and January, 1999. The achieved accuracy is between 0.01-0.03 mag, depending mainly on the target brightness.

Linking the formation and fate of exo-Kuiper belts within solar system analogues [PDF]
, 2020 Escalating observations of exo-minor planets and their destroyed remnants both passing through the solar system and within white dwarf planetary systems motivate an understanding of the orbital history and fate of exo-Kuiper belts and planetesimal discs.

An Objective Classification Scheme for Solar-System Bodies Based on Surface Gravity
GalaxiesWe introduce succinct and objective definitions of the various classes of objects in the solar system. Unlike the formal definitions adopted by the International Astronomical Union in 2006, group separation is obtained from measured physical properties ...

Discovery, Observational Data and the Orbit of the Transneptunian Object (420356) Praamžius
Open Astronomy, 2016 A project for astrometric and photometric observations of asteroids with the VATT telescope on Mt. Graham is described. One of the most important results is the discovery of the Transneptunian object (420356) Praamžius. We computed its orbit applying 198
