... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

... Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: Interferometric studies of the mass-loss process from cool evolved stars . ... Observing with ESO Telescopes . ... Cool evolved stars of different inital masses and thus luminosities loose considerable amounts of processed material and dust into the interstellar medium. ... However, the detailed mass-loss process is surprisingly little understood for most of these sources. ... Return to list of thesis topics . ...

. Although this design reduces the vignetting seen at the NA2 guider. We do not have a good feeling yet what the effect might be on scattered light at the focal plane.

. This section describes how to convert raw correlator data to our standard archive format. From there is it relatively easy to obtain either arrival times or to study polarization. The data reduction is a multistage process. You must learn about each in turn. Note: production and reduction of the correlator data uses the environment variables OBSDATA, OBSDIR, and fptmpool a lot. Booking is in OBSDIR, data goes into OBSDATA and the finished archives end up in fptmpool. (You need a $ sign in front of them) .

... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

... Although many of the images are used for teacher-driven activities, students do have the opportunity to work with scientists on original research projects. ... The primary goal is to have teachers experience astronomy research and then to bring the research data into their classrooms via the internet. ... They also learn how to process their data, build a solar telescope to take home to their classrooms, and learn background information from astronomers in each of the three research areas. ...
