Temperature Diagnostics of Chromospheric Fibrils using DKIST/ViSP Observations: K-Means Clustering Approach
Sanjay Gosain
The chromosphere is a critical layer of the solar atmosphere situated between the photosphere and the corona. Studying its temperature structure is important to understand the comp…
The Multiview Observatory for Solar Terrestrial Science (MOST)
N. Gopalswamy, S. Christe, S. F. Fung +54
We report on a study of the Multiview Observatory for Solar Terrestrial Science (MOST) mission that will provide comprehensive imagery and time series data needed to understand the…
Fast Inversion of Solar Ca II Spectra in Non-Local Thermodynamic Equilibrium
C. Beck, S. Gosain, C. Kiessner
Present day solar imaging spectrometers typically yield a few hundred million spectra in one hour of observing time. This number will increase by an order of magnitude for future i…
Astro2020 Science White Paper: Synoptic Studies of the Sun as a Key to Understanding Stellar Astrospheres
Valentin Martinez Pillet, Frank Hill, Heidi Hammel +11
Ground-based solar observations provide key contextual data (i.e., the 'big picture') to produce a complete description of the only astrosphere we can study in situ: our Sun's heli…
Spectral magnetic helicity of solar active regions between 2006 and 2017
Sanjay Gosain, Axel Brandenburg
We compute magnetic helicity and energy spectra from about 2485 patches of about 100 megameters (Mm) side length on the solar surface using data from Hinode during 2006--2017. An e…
High-resolution Observations of Halpha Spectra with a Subtractive Double Pass
C. Beck, R. Rezaei, D. Prasad Choudhary +3
High-resolution imaging spectroscopy in solar physics has relied on Fabry-Perot Interferometers (FPIs) in recent years. FPI systems, however, get technically challenging and expens…
