Tentative detection of circularly polarized bursty radio emissions from the HD 189733 exoplanetary system using NenuFAR beamformed observations
Jake D. Turner, Philippe Zarka, Jean-Mathias Grießmeier +4
Observing auroral radio emission is one of the most promising methods for detecting exoplanetary magnetic fields, which provide valuable insights into planetary interiors, atmosphe…
Disintegration of Long-Period Comet C/2021 A1 (Leonard)
David Jewitt, Yoonyoung Kim, Michael Mattiazzo +3
We present imaging observations of the disintegrating long-period comet C/2021 A1 (Leonard). High resolution observations with Hubble Space Telescope show no evidence for surviving…
Stellar occultations enable milliarcsecond astrometry for Trans-Neptunian objects and Centaurs
F. L. Rommel, F. Braga-Ribas, J. Desmars +66
Trans-Neptunian objects (TNOs) and Centaurs are remnants of our planetary system formation, and their physical properties have invaluable information for evolutionary theories. Ste…
Observational Investigation of the 2013 Near-Earth Encounter by Asteroid (367943) Duende
Nicholas Moskovitz, Conor Benson, Daniel Scheeres +20
On 15 February 2013, the asteroid 367943 Duende (2012 DA14) experienced a near-Earth encounter at an altitude of 27,700 km or 4.2 Earth radii. We present here the results of an ext…
YORP and Yarkovsky effects in asteroids (1685) Toro, (2100) Ra-Shalom, (3103) Eger, and (161989) Cacus
J. Durech, D. Vokrouhlicky, P. Pravec +22
The rotation states of small asteroids are affected by a net torque arising from an anisotropic sunlight reflection and thermal radiation from the asteroids' surfaces. On long time…
The First Planetary Microlensing Event with Two Microlensed Source Stars
D. P. Bennett, A. Udalski, C. Han +64
We present the analysis of microlensing event MOA-2010-BLG-117, and show that the light curve can only be explained by the gravitational lensing of a binary source star system by a…
