On the 2001 Splitting of the Nucleus of 51P/Harrington
The nucleus of 51P/Harrington suffered a major splitting event in Autumn 2001 discovered by amateur José Manteca. The light curve and separation of the...
On the Dust Environment of Main-Belt Comet 313P/Gibbs
We present observations carried out using the 10.4 m Gran Telescopio Canarias and an interpretative model of the dust environment of activated asteroid 313 P...
Oort cloud perturbations as a source of hyperbolic Earth impactors
The observation of interstellar objects 1I/'Oumuamua and 2I/Borisov suggests the existence of a larger population of smaller projectiles that impact our planet...
Comets may have played an important role in depositing the organic matter that, between 4,6 and 3,6 billion of years ago, allowed the formation of life on the...
Origin of two primitive NEAs: (3200) Phaethon and 1998 RQ36
Understanding the composition and the nature of any asteroid approaching the Earth, and consequently potentially hazardous, is a matter of general interest...
Outburst activity in comets - II. A multiband photometric monitoring of comet 29P/Schwassmann-Wachmann 1
We have carried out a continuous multiband photometric monitoring of the nuclear activity of comet 29P/Schwassmann-Wachmann 1 from 2008 to 2010. Our main aim...
The authors present the results of narrow-band filter photometry of Periodic Comet Faye obtained from Estacion Astronomica "Dr. Carlos U. Cesco" of Felix...
Physical and dynamical characterization of hyperbolic comet C/2017 U7 (PANSTARRS)
We present here a dynamical and observational study of the comet C/2017 U7 (PANSTARRS). This comet was discovered in 2017 and found to have a hyperbolic orbit...
Planet Hunters IX. KIC 8462852 - where's the flux?
Over the duration of the Kepler mission, KIC 8462852 was observed to undergo irregularly shaped, aperiodic dips in flux of up to ˜20 per cent. The dipping...
