The Absolute Magnitude of RR Lyraes: from HIPPARCOS Parallaxes and Proper Motions
Solano, E.
We have used HIPPARCOS proper motions and the method of Statistical Parallax to estimate the absolute magnitude of RR Lyrae stars. In addition, we have used the HIPPARCOS parallax of RR Lyr itself to determine its absolute magnitude. These two results are in excellent agreement with each other and give a zero-point for the RR Lyrae Mv,[…

ISO Observations of Classical Novae
Kessler, M. F.; Clavel, J.; Metcalfe, L. +8 more
We describe the ISO programme to observe classical novae. The programme includes observations of novae during and shortly after eruption, and old novae. ISO observations of far infrared fine structure lines are providing us with information about physical conditions in nova ejecta which complement and extend knowledge obtained from ground-based ob…

Distance Scales After HIPPARCOS
Feast, M. W.
A general review is given of the use of Hipparcos data to calibrate basic distance indicators.
Infrared Observations of High-Mass X-Ray Binaries
Waters, L. B. F. M.; van Loon, J. Th.; Kaper, L. +2 more
We present the first results of our ISO program on High-Mass X-ray Binaries (HMXBs). Infrared photometry, obtained at different aspect angles of the systems, is used to investigate the massive star's disrupted stellar wind and the accretion flow towards the compact X-ray source. Scenarios for massive binary evolution predict that HMXBs receive a l…
