Implications for the Formation of 2005 UD from a New Convex Shape Model

Jay K. Kueny, Colin Orion Chandler, Maxime Devogèle +15

(155140) 2005 UD has a similar orbit to (3200) Phaethon, an active asteroid in a highly eccentric orbit thought to be the source of the Geminid meteor shower. Evidence points to a…

(3200) Phaethon Polarimetry in the Negative Branch: New Evidence for the Anhydrous Nature of the DESTINY+ Target Asteroid

Jooyeon Geem, Masateru Ishiguro, Jun Takahashi +23

We report on the first polarimetric study of (3200) Phaethon, the target of JAXA's DESTINY mission, in the negative branch to ensure its anhydrous nature and to derive an accur…

Masses, bulk densities, and macroporosities of asteroids (15) Eunomia, (29) Amphitrite, (52) Europa, and (445) Edna based on Gaia astrometry

Lauri Siltala, Mikael Granvik

Gaia Data Release 2 (DR2) includes milliarcsecond-accuracy astrometry for 14,099 asteroids. We explore the practical impact of this data for the purpose of asteroid mass and orbit…

Polarimetric Properties of the Near--Sun Asteroid (155140) 2005 UD in Comparison with Other Asteroids and Meteoritic Samples

Masateru Ishiguro, Yoonsoo P. Bach, Jooyeon Geem +26

The investigation of asteroids near the Sun is important for understanding the final evolutionary stage of primitive solar system objects. A near-Sun asteroid, (155140) 2005 UD, ha…

Mass and Density of Asteroid (16) Psyche

Lauri Siltala, Mikael Granvik

We apply our novel Markov-chain Monte Carlo (MCMC)-based algorithm for asteroid mass estimation to asteroid (16) Psyche, the target of NASA's eponymous Psyche mission, based on clo…

Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds

Gaia Collaboration, X. Luri, L. Chemin +417

We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…

Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry

Gaia Collaboration, S. A. Klioner, F. Mignard +414

Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quali…

Asteroid mass estimation with the robust adaptive Metropolis algorithm

L. Siltala, M. Granvik

The bulk density of an asteroid informs us about its interior structure and composition. To constrain the bulk density one needs an estimate for the mass of the asteroid. The mass…

Detection of a gamma-ray flare from the high-redshift blazar DA 193

Vaidehi S. Paliya, M. Ajello, R. Ojha +10

High-redshift () blazars are the most powerful members of the blazar family. Yet, only a handful of them have both X-ray and -ray detection, thereby making it difficult to…

Gaia Data Release 2. Summary of the contents and survey properties

Gaia Collaboration, A. G. A. Brown, A. Vallenari +4

We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…

Gaia Data Release 2. Short-timescale variability processing and analysis

M. Roelens, L. Eyer, N. Mowlavi +13

The Gaia DR2 sample of short-timescale variable candidates results from the investigation of the first 22 months of Gaia photometry for a subsample of sources at the Gaia faint end…

Gaia Data Release 2: Properties and validation of the radial velocities

D. Katz, P. Sartoretti, M. Cropper +51

For Gaia DR2 (GDR2), 280 million spectra, collected by the RVS instrument on-board Gaia, were processed and median radial velocities were derived for 9.8 million sources brighter t…

Gaia Data Release 2: Photometric content and validation

D. W. Evans, M. Riello, F. De Angeli +9

Aims. We describe the photometric content of the second data release of the Gaia project (Gaia DR2) and its validation along with the quality of the data. Methods. The validation w…

Asteroid mass estimation using Markov-chain Monte Carlo

L. Siltala, M. Granvik

Estimates for asteroid masses are based on their gravitational perturbations on the orbits of other objects such as Mars, spacecraft, or other asteroids and/or their satellites. In…

Time series analysis of long-term photometry of BM Canum Venaticorum

L. Siltala, L. Jetsu, T. Hackman +10

Studying RS CVn binaries is challenging, because in addition to spot activity, other effects such as mass transfer between the components and gravitational distortion of their sphe…
