Estimating Magnetic Filling Factors From Simultaneous Spectroscopy and Photometry: Disentangling Spots, Plage, and Network

T. W. Milbourne, D. F. Phillips, N. Langellier +21

State of the art radial velocity (RV) exoplanet searches are limited by the effects of stellar magnetic activity. Magnetically active spots, plage, and network regions each have di…

The spectral impact of magnetic activity on disk-integrated HARPS-N solar observations: exploring new activity indicators

A. P. G. Thompson, C. A. Watson, R. D. Haywood +21

Stellar activity is the major roadblock on the path to finding true Earth-analogue planets with the Doppler technique. Thus, identifying new indicators that better trace magnetic a…

An ultra-short period rocky super-Earth orbiting the G2-star HD 80653

G. Frustagli, E. Poretti, T. Milbourne +26

Ultra-short period (USP) planets are a class of exoplanets with periods shorter than one day. The origin of this sub-population of planets is still unclear, with different formatio…

Testing the Spectroscopic Extraction of Suppression of Convective Blueshift

M. Miklos, T. W. Milbourne, R. D. Haywood +21

Efforts to detect low-mass exoplanets using stellar radial velocities (RVs) are currently limited by magnetic photospheric activity. Suppression of convective blueshift is the domi…

Sensitivity of low-degree solar p modes to active and ephemeral regions: frequency shifts back to the Maunder Minimum

William J. Chaplin, Rachel Howe, Sarbani Basu +7

We explore the sensitivity of the frequencies of low-degree solar p-modes to near-surface magnetic flux on different spatial scales and strengths, specifically to active regions wi…

Temporal evolution and correlations of optical activity indicators measured in Sun-as-a-star observations

J. Maldonado, D. F. Phillips, X. Dumusque +29

(Abridged) We perform a detailed study of the main optical activity indicators (Ca II H & K, Balmer lines, Na I D D, and He I D) measured for the Sun…
