New precise positions in 2013–2019 and a catalog of ground-based astrometric observations of 11 Neptunian satellites (1847–2019) based on Gaia-DR2 [PDF]
Context. Developing high-precision ephemerides for Neptunian satellites requires not only the continuation of observing campaigns but also the collection and improvement of existing observations. So far, no complete catalogs of observations of Neptunian satellites are available. Aims.

Close-in satellite detections in the trans-Neptunian region: the special case of Varuna.
Photometric techniques can be used to reveal the existence satellites around solar system bodies, but such methods have not been applied to Trans-neptunian objects (TNOs). Specifically, using rotational light-curves it is possible to reveal satellites much closer-in than using the direct imaging technique, and thus helping to remove biases in our ...

Capture of satellites during planetary encounters [PDF]
Context.Single-binary scattering may lead to an exchange where the single object captures a component of the binary, forming a new binary. This has been well studied in encounters between a star–planet pair and a single star.Aims.Here we explore the application of the exchange mechanism to a planet–satellite pair and another planet in the gravitational

JWST Spectrophotometry of the Small Satellites of Uranus and Neptune [PDF]
We use 1.4–4.6 μ m multiband photometry of the small inner Uranian and Neptunian satellites obtained with the James Webb Space Telescope’s near-infrared imager NIRCam to characterize their surface compositions.

Control of colocated geostationary satellites [PDF]
Control of the inter-satellite distances within a cluster of colocated satellites located in the same GEO window is examined with regards to the close approaches between pairs of satellites. Firstly, the orbital evolution and station keeping control of a

Colors of Irregular Satellites of Saturn with DECam [PDF]
We report g - r and r - i new colors for 21 Saturn Irregular Satellites; among them, four previously unreported. This is the highest number of Saturn Irregular satellites reported in a single survey.

What If Planet Nine Has Satellites?
In the past decade, numerical simulations started to reveal the possible existence of Planet Nine in our solar system. The Planet Nine scenario can provide an excellent explanation for the clustering in orbital elements for Kuiper Belt objects.
