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...
Pre-perihelion monitoring of interstellar comet 2I/Borisov
The discovery of interstellar comet 2I/Borisov offered the unique opportunity to obtain a detailed analysis of an object coming from another planetary system...
Primitive materials preserved in meteorites and comets: clues on the stellar sources producing short-lived nuclides and presolar grains
Short-lived nuclides (SLNs) were incorporated to the solar nebula at the time of condensation of the first minerals from the vapor phase. The study of the...
