SN 1989B Light Curve Analysis. ... In the light curve depicting their observations, definite trends are noted, here is a "thumb-nail" analysis of the the magnitude estimations of the bright SN (1989B) in the galaxy NGC 3627 (M66). ... The observations were inserted against the V magnitude templete of BL, CCD photometric data, (Wells et. al, (1994) and a color trend (B-V) histogram of the mean type Ia SN (BL)(nutemp.gif). Key Words: Amateur Observations, Supernova, Magnitude Estimates, 1989B . ...

... We Fourier analysed Hubble Telescope Crab pulsar data obtained with the High Speed Photometer in October 1993. A weak modulation at frequency Hz is detected. We found a strong correlation between this result and the Fourier transform result of stroboscopic Crab pulsar data obtained in December 1994 at the 1.82m telescope of Asiago observatory (University of Padua, Italy). ... We found that both data show a weak modulation at the period of 60 seconds. ... The corresponding frequency is Hz . ...

... Next: An IRAF-Independent Interface Up: Software Systems Previous: A New PROS . ... We present a high-level representation of the packages and tasks within IRAF/PROS. ... We have produced a high-level overview of PROS. ... The incremental stages were the short-term goals: a project overview diagram (i.e., an organizational diagram of software modules); high-level diagram (i.e., a bubble diagram of each module in the system); and unifying element tables (i.e., tables of task vs. software attributes)....

I), a short history on the five earlier WR catalogues, improved spectral classification, finding charts, a discussion on related objects, and a review of the status of Wolf-Rayet stars research. The apendix presents a bibliography on most of the Wolf-Rayet literature published since 1867. ...

... I present results from several seasons of photometric observations of X--ray sources in the Orion OB1a and OB1b star formation regions. The initial goal was to measure the rotational periods of several dozen pre--main sequence (PMS) stars. ... Infrared and optical data confirm that 90% of the X--ray sources are PMS and about 10% of the PMS stars may have disks. ... I find rotation periods for five stars at confidence of greater than 99.9/ greater than 99/ at much lower confidence. ...

XMM-Newton Science Analysis System . ... EQPOS' refers to equatorial coordinates [ ra, dec ]. DET' coordinates refers to the CAMCOORD2 system, but expressed in units of 0.05 arcsec instead of mm, as these are the units in which the detector coordinates are presented in the event list after pipeline processing (ie columns DETX and DETY ; see [ 5 ]). POS' coordinates refers to the projected sky coordinates of the source relative to the nominal pointing position, in units of 0.05 arcsec. ...

... The large body of near infrared observations presented in Testi et al. (1997; 1998) are analysed with the aim of characterizing the young stellar clusters surrounding Herbig Ae/Be stars. The results confirm the tendency of early Be stars to be surrounded by dense clusters of lower mass "companions", while Ae stars are never found to be associated with conspicuous groups. ... Only the most massive stars (10-20Msun) are found to be associated with dense (10^3 pc^-3) stellar clusters. ...
