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

New Limits on Fundamental Weak-Interaction Parameters from Superallowed
A new critical survey of all world data on superallowed beta decays provides demanding tests of, and tight constraints on, the weak interaction. In confirmation of the conserved vector current (CVC) hypothesis, the vector coupling coupling constant is ...

The CAMELS Multifield Data Set: Learning the Universe’s Fundamental Parameters with Artificial Intelligence [PDF]
We present the Cosmology and Astrophysics with Machine Learning Simulations (CAMELS) Multifield Data set (CMD), a collection of hundreds of thousands of 2D maps and 3D grids containing many different properties of cosmic gas, dark matter, and stars from ...

Fundamental parameters for 45 open clusters with Gaia DR2, an improved extinction correction and a metallicity gradient prior [PDF]
Reliable fundamental parameters of open clusters (OCs) such as distance, age, and extinction are key to our understanding of Galactic structure and stellar evolution.

On the Measurement of Fundamental Parameters of White Dwarfs in the Gaia Era [PDF]
We present a critical review of the determination of fundamental parameters of white dwarfs discovered by the Gaia mission. We first reinterpret color–magnitude and color–color diagrams using photometric and spectroscopic information contained in the ...

Revisiting the Fundamental Parameters of 49 New Star Clusters in Gaia DR2
Reliable fundamental parameters of star clusters such as distance modulus, metallicity, age, extinction, and binary fraction are of key importance for astrophysical studies. Although a lot of new star clusters were identified from the data of, e.g., Gaia
