SDSS-IV MaStar: Determination of Stellar Parameters Using Bayesian Averaging
Yan-Ping Chen, Renbin Yan, Szabolcs Mészáros +12
We present the stellar parameters for 59,266 high-quality spectra of 24,130 unique stars from the MaNGA Stellar Library (MaStar) in the Sloan Digital Sky Survey (SDSS) Data Release…
A Test of FeH Line Parameters using DR19 APOGEE spectra of Benchmark M Dwarfs
Anderson Silva-Andrade, Diogo Souto, Katia Cunha +9
Recent studies have suggested a mismatch of up to 0.20 dex between iron abundances derived from Fe I and FeH lines in the H-band spectra of M dwarfs, and in this work we investigat…
Analysis of Short-term Solar Activity Variability and Estimating the Timings of the Next Enhanced Bursts
Juie Shetye, Mausumi Dikpati
We present a hybrid forecasting strategy that combines numerical modeling, statistical forecasting, and machine learning methods to predict enhanced bursts of solar activity. These…
Reevaluating thermal instability in a uniform plasma: an extended analysis of instability domains
Varsha Felsy, Ramon Oliver, Jaume Terradas +3
Thermal instability plays a crucial role in the dynamics of astrophysical plasmas. Building upon the foundational work of G. B. Field (1965) and the subsequent analysis by T. Water…
Unipolarity of the solar magnetic field in equatorial coronal holes
Khagendra Katuwal, R. T. James McAteer
A study of the unbalanced magnetic polarity distribution of 70 coronal holes was performed. Data from the Helioseismic and Magnetic Imager (HMI) were used to examine the photospher…
Citizen CATE 2024: Extending Totality During the 8 April 2024 Total Solar Eclipse with a Distributed Network of Community Participants
Sarah A. Kovac, Amir Caspi, Daniel B. Seaton +240
The Citizen CATE 2024 next-generation experiment placed 43 identical telescope and camera setups along the path of totality during the total solar eclipse (TSE) on 8 April 2024 to…
