The California-Kepler Survey. XI. A Survey of Chromospheric Activity through the Lens of Precise Stellar Properties [PDF]
Surveys of exoplanet host stars are valuable tools for assessing population level trends in exoplanets, and their outputs can include stellar ages, activity, and rotation periods.

Fictions, Conditionals, and Stellar Astrophysics [PDF]
This article argues in favour of an inferential role for fictions in scientific modelling. The argument proceeds by means of a detailed case study, namely models of the internal structure of stars in stellar astrophysics.

Tracing kinematic (mis)alignments in CALIFA merging galaxies : Stellar and ionized gas kinematic orientations at every merger stage [PDF]
J.M.A. and V.W. acknowledge support from the European Research Council Starting Grant (SEDmorph; P.I. V. Wild).We present spatially resolved stellar and/or ionized gas kinematic properties for a sample of 103 interacting galaxies, tracing all merger ...

Influence of surface stressing on stellar coronae and winds [PDF]
STFC funding has supported this research.The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-scale surface magnetic fields that ...

Opacity calculation for target physics using the ABAKO/RAPCAL code [PDF]
Radiative properties of hot dense plasmas remain a subject of current interest since they play an important role in inertial confinement fusion (ICF) research, as well as in studies on stellar physics.

From theoretical stellar spectra to realistic models of the Milky Way : a never ending Odyssey [PDF]
The last chapter is dedicated to the compilation of the results and the discussion about the success of - but also about the problems that have arisen during - and in part also survived - this work. The main goal of this thesis was, firstly, to convert

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