Stokes inversion techniques are very powerful methods for obtaining information on the thermodynamic and magnetic properties of solar and stellar atmospheres...
Bimodal regime in young massive clusters leading to subsequent stellar generations
Massive stars in young massive clusters insert tremendous amounts of mass and energy into their surroundings in the form of stellar winds and supernova ejecta...
Calibrating HMI Magnetograms Using an End-to-end Magnetograph Model
Numerous solar and space science and operations projects rely heavily on accurate, consistent magnetic field measurements from the solar surface. These projects...
Capabilities of bisector analysis of the Si I 10 827 Å line for estimating line-of-sight velocities in the quiet Sun
We examine the capabilities of a fast and simple method to infer line-of-sight (LOS) velocities from observations of the photospheric Si I 10 827 Å line. This...
Center-to-Limb Variation of Solar Three-dimensional Hydrodynamical Simulations
We examine closely the solar center-to-limb variation of continua and lines and compare observations with predictions from both a three-dimensional (3D)...
Center-to-limb variations of the He I 10 830 Å triplet
We present high-resolution spectroscopic observations of the quiet-Sun center-to-limb variations (CLV) of the He I triplet at 10 830 Å and the nearby Si I 10...
Characterizing the Purple Earth: Modeling the Globally Integrated Spectral Variability of the Archean Earth
Ongoing searches for exoplanetary systems have revealed a wealth of planets with diverse physical properties. Planets even smaller than the Earth have already...
Chromospheric Diagnosis with Ca II Lines: Forward Modeling in Forward Scattering. I
This paper presents a synthetic tomography of the quiet solar chromosphere formed by spatial maps of scattering polarization. It has been calculated for the Ca...
Chromospheric Polarization in the Photospheric Solar Oxygen Infrared Triplet
We present multilevel radiative transfer modeling of the scattering polarization observed in the solar O i infrared triplet around 777 nm. We demonstrate that...
