ABSTRACT The Wide-field Infrared Survey Explorer (WISE) has surveyed the entire sky at
four infrared wavelengths with greatly improved sensitivity and spatial resolution compared …

When comet nuclei approach the Sun, the increasing energy flux through the surface layers
leads to sublimation of the underlying ices and subsequent outgassing that promotes the …

We present observations of the extended dust structures near the orbits of three short-period
comets: 2P/Encke, 22P/Kopff, and 65P/Gunn. The dust trails were originally discovered by …

Meteor science, aeronomy, and meteoritics are different disciplines with natural interfaces.
This paper is an effort to integrate the chemistry and mineralogy of collected interplanetary …

We present the results of ISOCAM observations performed on Comets 2P/Encke and
103P/Hartley 2, on 31 October 1997 and 1 January 1998, respectively. Images were …

Among the observed circumstellar dust envelopes a certain population, planetary debris
disks, is ascribed to systems with optically thin dust disks and low gas content. These …

Comet 46P/Wirtanen, prime target of ESA's ROSETTA mission, was successfully observed at
the Very Large Telescope Observatory in Chile: on 17 May 1999 with the Test Camera at the …

We present a thermal model of the nucleus of comet 46P/Wirtanen, constrained by the
temporal variations of the water production rate, in order to understand the activity on its …

The study of minor bodies of the Solar System is acquiring an increasing importance in
recent years thanks to new space missions, such as NEAR, and to new ground based …

We present the first gasdynamic simulations of the coma formed by the diffusion from a
comet nucleus interior of a volatile molecule at large heliocentic distance. The method used …
