WebGaia maps the galactic neighbourhood of the Sun in three dimensions by measuring positions in the sky, distances from Earth, and velocities of more than one billion stars. The Gaia data enable researchers to not only unravel the structure of the Milky Way in unprecedented detail but also to model the galaxy’s behaviour hundreds of millions of … Webthe GAIA wavelength region (λλ 8480-8740 ˚A). Note the presence of double peaked emission core in the CaII-triplet absorption lines and the P13, P14, P15 and P16 Paschen lines in emission. The absorption spectrum of the M giant is undisturbed and rich in FeI, TiI and MgI absorptions (apart from the forest of weak lines due to CN and TiO ...

Photometric system - Wikipedia

WebPhotometric system. In astronomy, a photometric system is a set of well-defined passbands (or optical filters ), with a known sensitivity to incident radiation. The sensitivity usually depends on the optical system, detectors and filters used. For each photometric system a set of primary standard stars is provided.
