The optical spectrum of the infrared source IRAS04296+3429 (optical counterpart - G0Ia star, V=14.2) was obtained with the echelle spectrometer PFES at the prime focus of the 6m telescope. ... 1995, Szczerba et al. 1996), our detailed modelling of its spectral energy distribution suggested that this source also should show the 30 m band. ... Stars: abundances - Stars: atmospheres - Stars: AGB and post-AGB - Stars: individual: IRAS04296+3429 . ... Spectral energy distribution . ...

... The spectroscopic modes of JWST NIRSpec and MIRI cover the main molecular bands of gas in planet-forming regions, tracing gas at temperatures of 100-1000 K. The integral field units of JWST will resolve the molecular emission in nearby protoplanetary disks, while the high sensitivity will allow observations of disks as far away as the Magellanic Clouds, constraining the chemistry of planet formation in a wide range of environments. ...

is split into spectral colours, corresponding to wavelength. Red light has long wavelengths, blue light has short wavelengths. from hot objects are continuous , like a rainbow . atoms only emit light of specific colours, revealing their fingerprints as a line spectrum . atoms in front of a hot object absorb light at these colours, giving an absorption spectrum . are predominantly absorption spectra . next

... The MMT optical spectra of SBS 0335-052W were obtained on 1996 January 19 with the Red Channel of the MMT Spectrograph. ... The linear scale is 1 = 263 pc at the distance to SBS 0335-052W of 54.1 Mpc. ... In Table 1, the observed line intensities and intensities corrected for interstellar extinction for SBS 0335-052W are shown along with extinction coefficient C (H ), observed flux of the H emission line, the equivalent width EW (H ) and equivalent width of absorption Balmer hydrogen lines EW (abs)....

... Previous: The Sliding-Cell Detection Program for Chandra X-ray Data . ... SLIM is a program developed at ST-ECF to simulate direct and slitless spectroscopic images. ... SLIM produces slitless spectroscopy simulations which include the effects of geometric distortions, fringing, and the field-dependence of the spectral dispersion. ... A slitless spectroscopy simulator was required to create realistic data of the upcoming Advanced Camera for Surveys (ACS) slitless spectroscopic modes. ...

... For SIMS (Secondary Ion Mass Spectrometry) analysis, a solid surface is bombarded by primary ions of some keV energy. ... The subsequent mass analysis of the emitted ions provides detailed information on the elemental and molecular composition of the surface. ... Extremely short ion pulses with a duration below . ... By rastering a fine-focussed ion beam over the surface, like an electron beam in an electron microprobe, mass resolved secondary ion images (chemical maps) can be obtained...
