State of the art, lightweight scientific experiments available for small to micro satellite missions

DOI: 10.1016/S0094-5765(99)00006-5 Bibcode: 1998AcAau..43..567M

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

DOI: 10.1023/A:1001543115388 Bibcode: 1998Ap&SS.255..481W

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

DOI: 10.1023/A:1002158210794 Bibcode: 1998Ap&SS.263..205S

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…

ISO SWS Spectroscopy of Proto-Planetary Nebulae

DOI: 10.1023/A:1001526612662 Bibcode: 1998Ap&SS.255..477H

Volk, Kevin; Kwok, Sun; Hrivnak, Bruce J.

We are obtaining low- (SWS01) and medium-resolution (SWS06) spectra of PPNe to investigate spectral features arising in these transitional objects. Three sources with the 21 µm feature have been confirmed, one new source found, and evidence of some substructure seen.

Observation of Microstructures in Planetary Nebulae

DOI: 10.1023/A:1001892819327 Bibcode: 1998Ap&SS.260..199D

Walsh, J. R.; Dudziak, G.

HST images of 5 Planetary nebulae showing small scale structures have been retrieved from the archives. For two PNe, NTT images were also available, and a double channel deconvolution technique applied to combine them to the HST images. A very precise flux calibration was performed on the HST images. Bow shocks and ionization effects are likely de…

Determination of highly accurate proper motions for 32 Hipparcos stars from photographic plates.

Bibcode: 1998KPCB...14..114W

Wang, S.; Wang, J.; Jin, W. +1 more

The authors have reduced 70 exposures on 32 photographic plates taken in four sky areas around the radio source 0316+413, the galaxy NGC 7302, the Pleiades astrometric standard region, and some other objects. The plates were obtained with the 40-cm astrographic refractor at the SheShan(Zô-Sé) station of the Shanghai Observatory. Using the PPM cata…

Atmospheric studies with spectro-imaging : prospects for the vims experiment on Cassini

DOI: 10.1016/S0032-0633(98)00004-X Bibcode: 1998P&SS...46.1305B

Bellucci, Giancarlo; Bellini, Barbara; Formisano, Vittoria

Spectroscopic observations of Jupiter and Saturn are here reported to show the possible applications to the future data acquired by the instrument VIMS ( Visible and Infrared Mapping Spectrometer) on board of the Cassini Mission. The following images and spectra have been acquired by a similar instrument called VNIR ( Visible and Near Infrared Spe…
