Abstract
After the Asymptotic Giant Branch or Red Supergiant stage of evolution, stars evolve rapidly from cool M-type to F-type and hotter before their final fates. We describe the use of the European Virtual Observatory to derive a set of properties based on published data which identify post-AGB transition objects. We then apply these selection criteria to find new candidate transition objects and investigate their images and spectra in more detail. Heterogenous data collections from all over the world can be tracked down, manipulated and compared using the internet. The internet is itself part of the telescope in a separate development, real-time correlation of E-VLBI observations of hydroxyl masers from the post-RSG star IRC + 10420.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
