Origins of the H, He I, and Ca II Line Emission in Classical T Tauri Stars
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
We perform local excitation calculations to obtain line opacities and emissivity ratios and compare them with observed properties of H, He I, O I, Ca II, and Na I lines to determine the density, tempe...

2010/3/9
We investigated the radiative emission of different types of solar features in the spectral range of the Ca II K line.
We analyzed full-disk 2k x 2k observations from the PSPT Precision Solar Photom...
