... 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. ...

... The effect is strongest in the most evolved, high-latitude supergiant V5112 Sgr=IRAS19500-1709, which has an extended structured envelope (Figs.1 and 2). In the optical spectrum of this object, the BaII ion lines are split into three components (Figs.3 and 4). ... Thus, we discovered for the first time the enrichment of the stellar envelope with heavy metals produced at the AGB stage. ...

On 19/20 October 1995 we used GRIM II to attempt spectroscopy of the 2.3 micron CO absorption band in stellar clusters. ... Read Noise Our typical backgrounds in 60s were about 100 DN (about 500 e), and so for faint objects our noise is utterly dominated by the read noise of about 110 e. We can think of three ways to improve this situation: integrate longer; reduce the read noise; or implement multiple reads. ... Flats The quartz lamps were too dim for flats. ...
