HAT-P-34b -- HAT-P-37b: Four Transiting Planets More Massive Than Jupiter Orbiting Moderately Bright Stars [PDF]

open access: yes, 2012
We report the discovery of four transiting extrasolar planets (HAT-P-34b - HAT-P-37b) with masses ranging from 1.05 to 3.33 MJ and periods from 1.33 to 5.45 days. These planets orbit relatively bright F and G dwarf stars (from V = 10.16 to V = 13.2).

Astrometric observations of comets and asteroids and subsequent orbital investigations [PDF]

open access: yes
The 155-cm reflector was used for observations of comets and minor planets on 28 nights during April-October. Twenty-two of the observations refer to comets, 62 to numbered minor planets (numbered, that is, by the end of the semester: only nine of them ...

People Love to Name Things: Current Trends in Naming Minor Planets

open access: yesВопросы ономастики
After several introductory remarks regarding the onomastic terminology used for names of celestial objects, the article proposes a semantic and a limited formal analysis of the minor planet names officially published in 2022 by the International ...

Observational data and orbits of the asteroids discovered at the Baldone Observatory in 2015–2018

open access: yesOpen Astronomy, 2020
This paper is devoted to the discovery of 37 asteroids at the Baldone Astrophysical Observatory (MPC 069) from 2015 to 2018, and one of dynamically interesting Mars-crosser (MC) observed at the Baldone Astrophysical Observatory, namely 2008 LX16.

Orbital properties of binary minor planets

open access: yes, 2010
Many binary minor planets (BMPs; both binary asteroids and binary Trans-Neptunians objects; TNOs) are known to exist in the Solar system. The currently observed orbital and physical properties of BMPs hold essential information and clues about their ...

A Survey for Massive Giant Planets in Debris Disks with Evacuated Inner Cavities [PDF]

open access: yes, 2007
The commonality of collisionally replenished debris around main sequence stars suggests that minor bodies are frequent around Sun-like stars. Whether or not debris disks in general are accompanied by planets is yet unknown, but debris disks with large ...

Precise CCD astrometric observations of minor planets and comets at the Belgrade observatory during 1997 [PDF]

open access: yesSerbian Astronomical Journal, 1998
73 precise astrometric positions of seven comets and two minor planets from MPC critical list - 1093 Freda and 4954 Eric - were obtained with the CCD equipped Askania astrograph (13.5/160) of Belgrade Astronomical Observatory.
