FOSSIL. III. Lightcurves of 371 Trans-Neptunian Objects

The Astrophysical Journal Supplement Series, 2023
From the first phase of the high-cadence Formation of the Outer Solar System: an Icy Legacy (FOSSIL) survey, we analyzed lightcurves, ranging from one to four nights in length, of 371 trans-Neptunian objects (TNOs) for periodicity.

The DECam Ecliptic Exploration Project (DEEP). VI. First Multiyear Observations of Trans-Neptunian Objects [PDF]

The Astronomical Journal, 2023
We present the first set of trans-Neptunian objects (TNOs) observed on multiple nights in data taken from the DECam Ecliptic Exploration Project. Of these 110 TNOs, 105 do not coincide with previously known TNOs and appear to be new discoveries.

Light Curves of Trans-Neptunian Objects from the K2 Mission of the Kepler Space Telescope [PDF]

The Astrophysical Journal Supplement Series, 2023
The K2 mission of the Kepler Space Telescope allowed the observations of light curves of small solar system bodies throughout the whole solar system. In this paper, we present the results of a collection of K2 trans-Neptunian object observations between ...

Causal evidence for the primordiality of colours in trans-Neptunian objects. [PDF]

Mon Not R Astron Soc Lett
The origins of the colours of trans-Neptunian objects (TNOs) represent a crucial unresolved question, central to understanding the history of our Solar system. Recent observational surveys revealed correlations between the eccentricity and inclination of

Shepherding in a Self-gravitating Disk of Trans-Neptunian Objects. [PDF]

Astron J, 2019
Abstract A relatively massive and moderately eccentric disk of trans-Neptunian objects (TNOs) can effectively counteract apse precession induced by the outer planets, and in the process shepherd highly eccentric members of its population into nearly stationary configurations that are antialigned with the disk itself. We were sufficiently

Chemical Evolution of Isotopically Labeled Carbon Dioxide (13CO2) Ice Exposed to Ionizing Radiation and Implications for Trans-Neptunian Objects

The Astrophysical Journal
We present results on the radiation chemistry of isotopically labeled carbon dioxide ( ^13 CO _2 ) ices induced by energetic electrons at 40 and 10 K to simulate the chemical evolution of carbon dioxide on trans-Neptunian objects exposed to galactic ...

Stellar occultations by trans-Neptunian objects

The Astronomy and Astrophysics Review
Stellar occultations provide a powerful tool to explore objects of the outer solar system. The Gaia mission now provides milli-arcsec accuracy on the predictions of these events and makes possible observations that were previously unthinkable ...
