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

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.

Asteroid spin-rate studies using large sky-field surveys

Geoscience Letters, 2017
Eight campaigns to survey asteroid rotation periods have been carried out using the intermediate Palomar Transient Factory in the past 3 years. 2780 reliable rotation periods were obtained, from which we identified two new super-fast rotators (SFRs ...

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

Ten New and Updated Multi-planet Systems, and a Survey of Exoplanetary Systems [PDF]

, 2009
We present the latest velocities for 10 multi-planet systems, including a re-analysis of archival Keck and Lick data, resulting in improved velocities that supersede our previously published measurements.

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

, 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 ...

Misaligned Rings Around Minor Planets with Moons

Universe
Recent observations have confirmed the existence of rings around minor bodies in the outer solar system. These objects may possess satellites as well. Here, we analytically investigate the interaction between such rings and satellites.
