Next: Radial velocity of the Up: Optical spectrum of IRAS04296 Previous: Observations and spectra reduction . ... 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. ...

... We carried out follow-up spectroscopy of 178 Case galaxies in the zone - 16 h , and - +38 ,classified in the Case catalog with some code, indicating the presence of the line [O III ] 5007, and not observed in the previous follow-up studies. ... We conclude that Case ELGs give the high fraction of BCGs -- about 60 % of all galaxies with strong enough emission lines, and more than 40 % of all Case galaxies, marked with some code of the presence of [O III ] line. ...

... On the basis of the previous (mostly intervening) H2 and OH detections, the limits reached here and in some previous surveys should be deep enough to detect molecular absorption according to their V - K colours. However, our survey makes the assumption that the reddening is associated with dust close to the emission redshift of the quasar and that the narrow millimetre component of this emission is intercepted by the compact molecular cores. ...

For historical reasons, it is useful to offer comparisons between the current WFPC2, and its predecessor WF/PC-1, which was returned to Earth in December 1993. Field format: WF/PC-1 contained 8 cameras and CCDs, each CCD having 800 x 800 pixels. ... Many differences derive from the fact that the WF/PC-1 CCDs were thinned, backside illuminated devices whereas the WFPC2 CCDs are thick, frontside illuminated devices. ... WFPC2 devices have much less CTE error, and hence no preflash is used. ...

... The task rgssources can either modify a previously-created source list or create a new one, depending on the value of the parameter filemode . If filemode =`create', the name of the newly created file is read from parameter srclist . If on the other hand filemode =`modify', the name of the existing file to be edited must instead be supplied to srclist . ... If filemode =`create', the name of the RGS instrument must be supplied via the parameter instexpid . ...

... Data from various satellite missions concerning emission lines formed at temperatures of 7 x 10 4 K to 1.3 x 10 5 K show oscillations in sunspots with frequencies in the range of 5.8-7.8mHz. ... All the observational data clearly indicate the presence of 3-minute oscillations in sunspots in spectral lines covering a vast temperature range from the low chromosphere to those lines normally associated with coronal temperatures. ...

Molecular Line Surveys with Arecibo Minchin et al. ... So far, the Arp 220 Spectral Survey has made the first detection of the pre-biotic molecule Methanamine (CH2 NH) outside of the Local Group, has seen three cm-wavelength transitions of HCN that had not previously been observed, has detected three transitions of excited OH that were not previously known in Arp 220 , has detected an absorption feature of either 18 OH or Formic Acid (HCOOH), and has seen a possible ...

... Many extragalactic objects for which radial velocities are desired display strong emission lines. ... EMSAO, a companion to the cross-correlation task XCSAO (Kurtz et al. 1992), was written to find emission lines automatically, compute redshifts for each identified line, and combine them into a single radial velocity. ... Figure: This EMSAO Summary page shows line centers and fit information for a night sky spectrum. ... To test EMSAO adequately, a lot of emission line spectra were needed. ...

... Since the reddening found for the stars in Table 13 was small, no reddening correction was attempted. ... These diamonds indicate the positions of very low mass, 3 Myr old, objects from the work of Burrows et al. ...
