Disentangling planetary orbits from stellar activity in radial-velocity surveys [PDF]

, 2013
The majority of extra-solar planets have been discovered (or confirmed after follow-up) through radial-velocity (RV) surveys. Using ground-based spectrographs such as High Accuracy Radial Velocity Planetary Search (HARPS) and HARPS-North, it is now ...

The Carnegie-Irvine Galaxy Survey. X. Bulges in Stellar Mass–based Scaling Relations

The Astrophysical Journal Supplement Series, 2022
We measure optical colors for the bulges of 312 disk galaxies from the Carnegie-Irvine Galaxy Survey and convert their previously available R -band structural parameters to stellar-mass parameters.

Classification of Stellar Spectra [PDF]

International Astronomical Union Colloquium, 1990
SummaryThe objectives of this exercise are to gain familiarity with the appearance of the spectra of stars, to understand some of the temperature and luminosity criteria used to classify spectra, and to gain insights into the relationship between the appearance of stellar spectra and physical conditions in stellar atmospheres.
