The rise time of the change of cometary brightness during its outburst
Wesołowski, Marcin
The paper presents a new method for determining the change in the brightness of a comet during an outburst in which particles are ejected into the coma at a uniform rate, i.e. via a long-lived jet. In the proposed approach, the mass flow rate by a jet and the time it takes to increase the brightness of the comet play key roles. Absolute values ado…
Optical observations and dust modelling of comet 156P/Russell-LINEAR
Aravind, K.; Halder, Prithish; Ganesh, Shashikiran +5 more
Comet 156P/Russell-LINEAR is a short period Jupiter family comet with an orbital period of 6.44 years. The results from spectroscopic, photometric, polarimetric observations and dust modelling studies are presented here. From the spectroscopic study, strong emissions from CN(Δν = 0) , C3 (λ 4050 Å), C2(Δν = + 1) and C2
Noble gases in Dome C micrometeorites - An attempt to disentangle asteroidal and cometary sources
Trieloff, Mario; Engrand, Cécile; Duprat, Jean +2 more
We have performed a comprehensive noble gas study, including the isotopes of krypton and xenon, on a set of micrometeorites (MMs) collected from surface snow at Dome C (DC) on the Antarctic plateau. He and Ne are generally dominated by a solar component, with lower 4He concentrations and 4He/20Ne ratios in crystall…
