The 2017 May 20 stellar occultation by the elongated centaur (95626) 2002 GZ

P. Santos-Sanz, J. L. Ortiz, B. Sicardy +56

We predicted a stellar occultation of the bright star Gaia DR1 4332852996360346368 (UCAC4 385-75921) (m= 14.0 mag) by the centaur 2002 GZ for 2017 May 20$^{\rm th}…

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…

Machine Learning for Searching the Dark Energy Survey for Trans-Neptunian Objects

B. Henghes, O. Lahav, D. W. Gerdes +56

In this paper we investigate how implementing machine learning could improve the efficiency of the search for Trans-Neptunian Objects (TNOs) within Dark Energy Survey (DES) data wh…

A multi-chord stellar occultation by the large trans-Neptunian object (174567) Varda

D. Souami, F. Braga-Ribas, B. Sicardy +41

We present results from the first recorded stellar occultation by the large trans-Neptunian object (174567) Varda that was observed on September 10, 2018. Varda belongs…

The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation

J. L. Ortiz, P. Santos-Sanz, B. Sicardy +90

Among the four known transneptunian dwarf planets, Haumea is an exotic, very elongated, and fast rotating body. In contrast to the other dwarf planets, its size, shape, albedo, and…

The large Trans-Neptunian Object 2002 TC from combined stellar occultation, photometry and astrometry data

J. L. Ortiz, P. Santos-Sanz, B. Sicardy +78

On 28th January 2018, the large Trans-Neptunian Object (TNO) 2002TC302 occulted a m15.3 star with ID 130957813463146112 in the Gaia DR2 stellar catalog. 12 positive occultati…

Testing the isotropy of the Dark Energy Survey's extreme trans-Neptunian objects

Pedro H. Bernardinelli, Gary M. Bernstein, Masao Sako +19

We test whether the population of "extreme" trans-Neptunian objects (eTNOs) detected in the Y4 Dark Energy Survey (DES) data exhibit azimuthal asymmetries which might be evidence o…

Dynamical Classification of Trans-Neptunian Objects Detected by the Dark Energy Survey

T. Khain, J. C. Becker, Hsing Wen Lin +52

The outer Solar System contains a large number of small bodies (known as trans-Neptunian objects or TNOs) that exhibit diverse types of dynamical behavior. The classification of bo…
