The Buildup of a Tightly Bound Comet Cloud around an Early Sun Immersed in a Dense Galactic Environment: Numerical Experiments
(Academic Press Inc Elsevier Science, 2000-06)
We simulate numerically the buildup of a comet reservoir around the early Sun assumed to be still immersed in the placental molecular gas that gave birth to it, and to be gravitationally bound to other young stars formed ...
Irradiation of nitrogen-rich ices by swift heavy ions: clues for the formation of ultracarbonaceous micrometeorites
(2015)
Context. Extraterrestrial materials, such as meteorites and interplanetary dust particles, provide constraints on the formation and evolution of organic matter in the young solar system. Micrometeorites represent the ...
Photometry of the Oort Cloud comet C/2009 P1 (Garradd): Pre-perihelion observations at 5.7 and 2.5 AU.
(Elsevier, 2016-02)
The aim of this paper is to contribute to the characterization of the general properties of the Long Period Comets (LPCs) family, and in particular to report on the dust environment of comet C/2009 P1 (Garradd).The comet ...
New orbits for Comets C/1960 M1 (Humason), C/1980 E1 (Bowell), and musings on extrasolar comets
(Universidad Nacional Autónoma de México. Instituto de Astronomía, 2013-04)
Se calculan órbitas nuevas para los Cometas Humasen (C/1960 M1) y Bowell (C/1980 E1). La órbita de Humasen se basa en 34 observaciones hechas durante 348 dias y para Bowell 203 observaciones hechas durante ocho años. ...
Mass extinctions, galactic orbits in the solar neighborhood and the Sun: a connection?
(Guarujá, 2014-03-14)
The orbits of the stars in the disk of the Galaxy, and their passages through the Galactic spiral arms, are a rarely mentioned factor of biosphere stability which might be important for long-term planetary climate evolution, ...
