Using limb darkening to measure fundamental parameters of stars [PDF]

Astronomy & Astrophysics, 2012
Context. Limb darkening is an important tool for understanding stellar atmospheres, but most observations measuring limb darkening assume various parameterizations that yield no significant information about the structure of stellar atmospheres. Aims. We use a specific limb-darkening relation to study how the best-fit coefficients relate to fundamental

Fundamental Parameters of Exoplanets and Their Host Stars

, 2013
For much of human history we have wondered how our solar system formed, and whether there are any other planets like ours around other stars. Only in the last 20 years have we had direct evidence for the existence of exoplanets, with the number of known exoplanets dramatically increasing in recent years, especially with the success of the Kepler ...

“X-Raying” a Be Star Disk: Fundamental Parameters of the Eclipsing Binary Be Star V658 Car

The Astrophysical Journal
Abstract With its two stellar eclipses and two disk attenuations per binary orbit, V658 Carinae stands out as the first clear eclipsing Be + sdOB system. This rare alignment offers a unique opportunity to probe the structure and dynamics of a Be star disk with unprecedented detail.

Symmetry in fundamental parameters of galaxies on the star-forming main sequence

Monthly Notices of the Royal Astronomical Society
ABSTRACT The Star-Forming Main Sequence (SFMS) serves as a critical framework for understanding galaxy evolution, highlighting the relationship between star formation rates (SFR) and stellar masses $M_*$ across cosmic time, for star forming galaxies.

Fundamental Parameters for Central Stars of 103 Infrared Bow Shock Nebulae

The Astrophysical Journal
Abstract Stellar bow shock nebulae are arcuate shock fronts formed by the interaction of radiation-driven stellar winds and the relative motion of the ambient interstellar material. Stellar bow shock nebulae provide a promising means to measure wind-driven mass loss, independent of other established methods. In this work, we characterize

The Fundamental Stellar Parameters of FGK Stars in the SEEDS Survey

, 2017
Large exoplanet surveys have successfully detected thousands of exoplanets to-date. Utilizing these detections and non-detections to constrain our understanding of the formation and evolution of planetary systems also requires a detailed understanding of the basic properties of their host stars.

Fundamental Parameters Of The Lowest Mass Stars To The Highest Mass Planets

, 2016
The physical and atmospheric properties of ultracool dwarfs are deeply entangled due to the degenerate effects of mass, age, metallicity, clouds and dust, activity, rotation, and possibly even formation mechanism on observed spectra. Accurate determination of funda- mental parameters for a wide diversity of objects at the low end of the initial mass ...
