There are several objects in this region: a B type star GSC 0625400181 surrounded by an HII region (object 2 in Fig.2), a star with a straight jet (object 3 in Fig.2), and a unique object SNO ...

We show that for both top and bottom normal incidences, the maximum absorbances could be above 85% at respective resonances. For both transverse electr ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
