cds-question@unistra.frinfrared-astronomyspectroscopyastronomical-modelsMany cosmic dust species, among them refractory oxides, form at temperatures higher than 300K. Nevertheless, most astrophysical studies are based on the room-temperature optical constants of solids, such as corundum and spinel. A more realistic approach is needed for these materials, especially in the context of modeling late-type stars. We aimed at deriving sets of optical constants of selected, astrophysically relevant oxide dust species with high melting points. A high-temperature, high-pressure cell and a Fourier-transform spectrometer were used to measure reflectance spectra of polished samples. For corundum ({alpha}-Al_2_O_3_), spinel (MgAl_2_O_4_), and {alpha}-quartz (SiO_2_), temperature-dependent optical constants were measured from 300K up to more than 900K. Small particle spectra were also calculated from these data.2013A&A...553A..81Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/553/A81CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/86/713 : IR spectroscopy of ices (Hudgins+, 1993)J/A+A/423/983 : Meteoritic nano-diamonds optical constants (Mutschke+, 2004)J/A+A/483/661 : Refractive index for silicon carbide (SiC) (Pitman+, 2008)J/ApJ/701/1347 : Optical constants of H_2_O-ice (Mastrapa+, 2009)J/ApJS/191/96 : IR spectra & optical constants of nitrile ices (Moore+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/553/A81https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/553/A81http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/553/A81https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/553/A81https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/553/A81http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/553/A81GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/A+A/553/A81/corund-eCombined table from original tablesrecnoRecord number assigned by the VizieR team.
