The physical properties of cometary nuclei observed today relate to their complex history
and help to constrain their formation and evolution. In this article, we review some of the …

Questions regarding how primordial or pristine the comets of the solar system are have been
an ongoing controversy. In this review, we describe comets' physical evolution from dust and …

Abstract'Oumuamua (1I/2017 U1) is the first object of interstellar origin observed in the solar
system. Recently, Micheli et al. reported that'Oumuamua showed deviations from a …

Before Rosetta, the space missions Giotto and Stardust shaped our view on cometary dust,
supported by plentiful data from Earth based observations and interplanetary dust particles …

So-called 'dark comets' are small, morphologically inactive near-Earth objects (NEOs) that
exhibit nongravitational accelerations inconsistent with radiative effects. These objects …

When comets approach the Sun, their surface is heated and the volatile species start to
sublimate. Due to the increasing gas pressure, dust is ejected off the surface, which can be …

In this work we combine several constraints provided by the crater records on Arrokoth and
the worlds of the Pluto system to compute the size-frequency distribution (SFD) of the crater …

Small bodies are among the best tracers of our Solar System's history. A large number of
space missions to small bodies (past and future) offer a unique opportunity to use these …

This paper presents two problems related to the ejection of particles from the surface of the
cometary nucleus. The first problem is related to the phase of quiet sublimation. This part of …

This study presents the first optical (420–930 nm) spectropolarimetric study of a sample of
large (≳ 100 km in diameter) C-complex asteroids in observing circumstances for which light …
