Spectropolarimetric Inversion in Four Dimensions with Deep Learning (SPIn4D). I. Overview, Magnetohydrodynamic Modeling, and Stokes Profile Synthesis Open
The National Science Foundation’s Daniel K. Inouye Solar Telescope (DKIST) will provide high-resolution, multiline spectropolarimetric observations that are poised to revolutionize our understanding of the Sun. Given the massive data volum…

Sequential coronographic low order Wave-front sensors Open
Coronagraphs are highly sensitive to wavefront errors, with performance degrading rapidly in the presence of low-order aberrations. Correcting these aberrations at the coronagraphic focal plane is key to optimal performance. We present two…

Poynting-Robertson-like Drag at the Sun’s Surface Open
The Sun's internal rotation Ω(r,Θ) has previously been measured using helioseismology techniques and found to be a complex function of colatitude θ and radius r. From helioseismology and observations of apparently "rooted" solar magnetic t…
