    Observational Constraints on Surface Characteristics of Comet Nuclei

    Observational Constraints on Surface Characteristics of Comet Nuclei Humberto Campins ([email protected] u) Lunar and Planetary Laboratory, University of Arizona Yanga Fernandez University of Hawai'i Abstract. Direct observations of the nuclear surfaces of comets have b een dicult; however a growing number of studies are overcoming observational challenges and yielding new information on cometary surfaces. In this review, we fo cus on recent determi- nations of the alb edos, re ectances, and thermal inertias of comet nuclei. There is not much diversity in the geometric alb edo of the comet nuclei observed so far (a range of 0.025 to 0.06). There is a greater diversity of alb edos among the Centaurs, and the sample of prop erly observed TNOs (2) is still to o small. Based on their alb edos and Tisserand invariants, Fernandez et al. (2001) estimate that ab out 5% of the near-Earth asteroids have a cometary origin, and place an upp er limit of 10%. The agreement between this estimate and two other indep endent metho ds provide the strongest constraint to date on the fraction of ob jects that comets contribute to the p opulation of near-Earth asteroids. There is a diversity of visible colors among comets, extinct comet candidates, Centaurs and TNOs. Comet nuclei are clearly not as red as the reddest Centaurs and TNOs. What Jewitt (2002) calls ultra-red matter seems to be absent from the surfaces of comet nuclei. Rotationally resolved observations of b oth colors and alb edos are needed to disentangle the e ects of rotational variability from other intrinsic qualities.

  • Early Observations of the Interstellar Comet 2I/Borisov

    Early Observations of the Interstellar Comet 2I/Borisov

    geosciences Article Early Observations of the Interstellar Comet 2I/Borisov Chien-Hsiu Lee NSF’s National Optical-Infrared Astronomy Research Laboratory, Tucson, AZ 85719, USA; [email protected]; Tel.: +1-520-318-8368 Received: 26 November 2019; Accepted: 11 December 2019; Published: 17 December 2019 Abstract: 2I/Borisov is the second ever interstellar object (ISO). It is very different from the first ISO ’Oumuamua by showing cometary activities, and hence provides a unique opportunity to study comets that are formed around other stars. Here we present early imaging and spectroscopic follow-ups to study its properties, which reveal an (up to) 5.9 km comet with an extended coma and a short tail. Our spectroscopic data do not reveal any emission lines between 4000–9000 Angstrom; nevertheless, we are able to put an upper limit on the flux of the C2 emission line, suggesting modest cometary activities at early epochs. These properties are similar to comets in the solar system, and suggest that 2I/Borisov—while from another star—is not too different from its solar siblings. Keywords: comets: general; comets: individual (2I/Borisov); solar system: formation 1. Introduction 2I/Borisov was first seen by Gennady Borisov on 30 August 2019. As more observations were conducted in the next few days, there was growing evidence that this might be an interstellar object (ISO), especially its large orbital eccentricity. However, the first astrometric measurements do not have enough timespan and are not of same quality, hence the high eccentricity is yet to be confirmed. This had all changed by 11 September; where more than 100 astrometric measurements over 12 days, Ref [1] pinned down the orbit elements of 2I/Borisov, with an eccentricity of 3.15 ± 0.13, hence confirming the interstellar nature.

A copy of the proposed, revised By-Laws should be in your mail soon. Read through them, and any proposed changes need to be communicated to me before the November meeting. Wally Pursell (who wrote the original and changed by-laws) and I worked last year on getting the By-Laws updated to the current BRAS policies, and we hope the revised By-Laws will need no revisions for a long time. We need more Globe at Night observations – we are behind in the observations compared to last year at this time.

  • How We Found About COMETS

    How We Found About COMETS

    How we found about COMETS Isaac Asimov Isaac Asimov is a master storyteller, one of the world’s greatest writers of science fiction. He is also a noted expert on the history of scientific development, with a gift for explaining the wonders of science to non- experts, both young and old. These stories are science-facts, but just as readable as science fiction.Before we found out about comets, the superstitious thought they were signs of bad times ahead. The ancient Greeks called comets “aster kometes” meaning hairy stars. Even to the modern day astronomer, these nomads of the solar system remain a puzzle. Isaac Asimov makes a difficult subject understandable and enjoyable to read. 1. The hairy stars Human beings have been watching the sky at night for many thousands of years because it is so beautiful. For one thing, there are thousands of stars scattered over the sky, some brighter than others. These stars make a pattern that is the same night after night and that slowly turns in a smooth and regular way. There is the Moon, which does not seem a mere dot of light like the stars, but a larger body. Sometimes it is a perfect circle of light but at other times it is a different shape—a half circle or a curved crescent. It moves against the stars from night to night. One midnight, it could be near a particular star, and the next midnight, quite far away from that star. There are also visible 5 star-like objects that are brighter than the stars.
