Towards understanding stellar variability at the sub m/s level: granulation-induced variability across the optical spectrum

Cis Lagae, Ginger Frame, Heather M. Cegla +5

Detecting the radial velocity signal of Earth-mass exoplanets requires the characterisation and removal of granulation-induced radial velocity variability from spectroscopic observ…

Three-dimensional Magnetic Structures of Ellerman Bombs revealed by SUNRISE III/SCIP

Yusuke Kawabata, Yukio Katsukawa, Masahito Kubo +37

Ellerman bombs (EBs) are widely recognized as photospheric and chromospheric signatures of magnetic reconnection. However, the three-dimensional (3D) magnetic topology has remained…

The Fe I 4377 Ã Line as a Solar Faculae Indicator: Insights from Spectral Ratio Analysis

Katlyn L. Hobbs, Christopher A. Watson, Jean C. Costes +21

Faculae are a dominant source of stellar activity noise in radial velocity measurements, yet their low contrast and broad surface distribution make them difficult to track in disc-…

Multi-Wavelength Diagnostics of Pre-Flare Evolution with Aditya-L1: From the Solar Chromosphere to the Corona

Adithya H. N., Sreejith Padinhatteeri, Soumya Roy +13

The pre-flare phase of solar flares provides important insight into the processes that drive active regions toward instability. We investigate chromospheric pre-flare activity usin…
