Observations of carbon monoxide in comet Hale-Bopp.

چکیده
The recently discovered comet Hale-Bopp (C/1995 01) sports a bright dust coma even though it is still far from the sun (presently 6 astronomical units). This feature has attracted considerable interest in the public and scientific arenas. The comet is headed toward perihelion at 0.92 astronomical unit in April 1997 and is widely expected to then become a spectacular naked-eye comet. With millimeter-wave observations, carbon monoxide (CO) has been identified as the driver for the early activity observed in Hale-Bopp.

Interferometric imaging of carbon monoxide in comet C/1995 O1 (Hale-Bopp): evidence for a strong rotating jet
Context. Observations of the CO J(1–0) 115 GHz and J(2–1) 230 GHz lines in comet C/1995 O1 (Hale-Bopp) were performed with the IRAM Plateau de Bure interferometer on 11 March, 1997. The observations were conducted in both single-dish (ON–OFF) and interferometric modes with 0.13 km s spectral resolution. Images of CO emission with 1.7 to 3′′ angular resolution were obtained. Aims. The ON–OFF and...
متن کاملWater Production and Release in Comet C/1995 O1 Hale–Bopp
Water (H2O) was detected in Comet C/1995 O1 Hale–Bopp on 10 dates between UT January 21.8 and May 1.2, 1997, using highresolution infrared spectroscopy. This is the first study of the heliocentric dependence of water released from a comet using direct detection of H2O itself. Production rates and rotational temperatures were measured, and the derived heliocentric dependence for the water produc...
متن کاملPhotometric behavior of comet Hale-Bopp (C/1995 O1) before perihelion.
Narrowband photometric observations of comet Hale-Bopp (C/1995 O1) between 25 July 1995 and 15 February 1997 indicated gas and dust production rates of 20 and 100 times greater, respectively, than observed at the same heliocentric distances for comet P/Halley in 1985. Hale-Bopp produced dust at a rate greater than has been observed for any other comet at any distance since at least 1977. On the...
متن کاملEvidence for Chemical Heterogeneity in the Nucleus of C/1995 O1 (hale–bopp)
We present an analysis of OH, CN, and C2 jets observed in the coma of Comet Hale– Bopp on UT April 22, 23, and 25, 1997. Monte Carlo models designed to simulate the gas jets were employed to analyze the nuclear active areas responsible for the observed coma gas jets. Our results indicate that four active areas are necessary to reproduce the CN and C2 jets while five active areas are required to...
متن کاملNew molecules found in comet C / 1995 O 1 ( Hale - Bopp ) Investigating the link between cometary and interstellar material
We present millimetre and submillimetre observations of comet C/1995 O1 (Hale-Bopp) undertaken near perihelion with the Caltech Submillimeter Observatory and the 30m telescope and Plateau-de-Bure interferometer of the Institut de Radioastronomie Millimétrique. From a spectral molecular survey, six new cometary molecular species have been identified for the first time in a comet: SO, SO2, HC3N, ...
