kd - The HST Treasury Program on Eta Carinae
... Detection of the secondary star is highly desirable because that would eliminate single-star models. Unfortunately, as we explained in sections 2—4 above, there is no proof that any emission seen with FUSE came from a second star. It’s not hard to imagine a single-star model. The equatorial photosph ...

Spin-Orbit Angles as a Probe to Orbital Evolution
... Fig. 1a & b show that the fraction of aligned to misaligned objects is larger when planets orbit stars that have a massive outer convective layer (red triangles) corresponding to Teff <6150 K. Tides are dissipated more effectively when there is an outer convective layer (Zahn 1977). Winn et al. (2010) ...

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.
