Calibration of the Classical Cepheid Period-Luminosity Relation from HIPPARCOS Data
Luri, X.; Figueras, F.; Torra, J. +3 more
The calibration of the classical Cepheid Period-Luminosity (PL) relation is a fundamental step for the determination of the cosmic distance scale. In this paper a calibration obtained from Hipparcos data is presented and used to estimate the LMC distance modulus. A value of 18.35m ± 0.13 is obtained.
Determination of Stellar Surface Temperature Using Ultraviolet Spectra
Choi, Young-Jun; Han, Wonyong; Kang, Young Woon +3 more
Color indexes and effective temperatures for 25 standard stars have been determined as a pilot project which show a relationship between color index and effective temperature in ultraviolet region. The effective temperature was determined by comparing energy distribution curves derived from the IUE low dispersion spectra with Kurucz atmosphere mod…
Spectroscopic Survey of δ SCT Stars
Solano, E.; Pintado, O. I.
The methods used to derive effective temperatures, projected rotational velocities and surface gravities of a sample of low and high-amplitude δ Sct stars are presented here. Effective temperatures were derived using Hα and Hβ line profiles whereas rotational velocities were calculated following the method described in Solano & Fernley (1997).…

State of the art, lightweight scientific experiments available for small to micro satellite missions
McKenna-Lawlor, Susan M. P.
A selection of light weight scientific instruments originally designed for major international missions but which, because of their modest resource requirements, can now in addition be flown aboard ' small' to ' micro' satellites are, briefly, described. These instruments have the capability to either make measurements of constituents of the Earth…
Observations of the Dust Around Evolved Stars
Walker, H. J.; Richards, P. J.; Heinrichsen, I.
ISOPHOT has been used to obtain low resolution spectra from 2.5µm to 5µm and 5.8µm to 11.6µm and multi-aperture photometry at 60µm of several evolved stars; oxygen-rich and carbon-rich (including the peculiar carbon-rich stars R CrB and RY Sgr). R CrB was observed early in the ISO mission, 3 weeks after it had been at minimum light. Another spectr…

Far-Infrared CO Rotational Lines in the Orion Molecular Cloud
Cernicharo, J.; González-Alfonso, E.; Lefloch, B. +3 more
We present a high signal-to-noise grating spectrum between 43-196.9 µm of the Orion molecular cloud towards the massive star-forming region IRc2, obtained with the Long Wavelength Spectrometer (LWS) on board the Infrared Space Observatory (ISO). CO lines up to J=20-19 have been detected around Orion-IRc2, while in the central position higher…
