However, molecular emission features are only very rarely observed in the optical spectra of PPNe. ... On the other hand, it is well known that cometary nuclei spectra show prominent Swan band emission. In both spectra of IRAS04296 we have discovered strong emission in the (0;0) and (0;1) bands of the Swan system of the molecule. ... Now consider the case of IRAS04296. ...

... Advises . Contact Advises . As an advise for amateurs we would like to underline: if it's possible, try to observe 3 asteroid positions per night and do not neglect to observe the Numbered Minor Planets in your telescope field of view as a "by product" of your observational programs. ... We think such estimations ought to be produced every morning after CCD observations of the moving celestial objects by observer himself. ...

Next: Observations Up: The Nuclear Region: HI Previous: The Nuclear Region: HI . There are mainly two questions to be addressed: 1) What causes the large velocity width (several hundred kms -1 ) of the absorption lines detected against the nuclear regions of galaxies? 2) Why are the absorption line widths observed against the nuclear radio continuum similar to those measured in emission over the whole extent of the galaxy? ...

In the 1960s astronomer Peter van de Kamp announced the discovery of two planets in orbit about BarnardтАЩs Star! ... Then another researcher used the same plates as van de Kamp to study another tiny M class red dwarf in Draco called Gliese 793 and found that it and BarnardтАЩs Star appeared to wobble in synch....

... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

... Since planets are expected to form out of the material in disks around young stars, the formation of a planet will thoroughly alter the structure of the circumstellar disk of their host star, forming significant gaps in the radial distribution of matter around the star. Additionally, processing of solids (annealing/crystallization) and changes in the overall gas/dust ratio are thought to happen during the planet formation process and are believed to alter the observational signature of the disk. ...

... Staff . ... Cosmic dust has been observed both in emission and extinction everywhere in our Galaxy as well as in many other galaxies. ... Dust grains are classically thought to form in the winds of Asymptotic Giant Branch (AGB) stars. However, nowadays there is increasing observational evidence for notable dust formation in Supernovae (SNe). ... Hence the observed dust mass of 0.7вИТ0.9M вКЩ in this source can be safely considered as indicative of the mass of freshly formed dust in SN ejecta. ...

With stellar occultation data we can also probe for close companions and possible tenuous atmospheres. ... Copyright (c) Amateur Telescope Makers of Boston, Inc. ...

... The concept of continuous solar wind developed in 1950's. First, Biermann (1951, 1957) observed comet tails as they passed close to the Sun , and explained the observed tail deflection by a continuous flux of protons from the Sun. Then Parker (1959) showed that the solar corona must expand, and called the outward streaming coronal gas 'solar wind'. ... The expanding solar wind drags also the solar magnetic field outward, forming what is called the interplanetary magnetic field (IMF) . ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...
