... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

... 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. ...

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).

The total radiative power output from the hot outer layers of six late-type stars (of different spectral types and luminosity class) is derived via an emission measure technique. This analysis was based on observational data from the spectral range 100A to 3000A obtained as a result of three separate satellite missions, i.e. Hubble Space Telescope, International Ultraviolet Explorer and the Extreme Ultraviolet Explorer. ...

... Science Users Information > Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: Planetary Nebulae and HII regions in the Elliptical Galaxy NGC 5128 . ... NGC 5128 is the closest example of a giant early type (elliptical or S0) galaxy. Although often dubbed as a peculiar elliptical galaxy since it has a dust lane with recent star formation and an active galactic nucleus, the majority of early type galaxies have similar structures as revealed by recent surveys. ...
