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…
Synthetic disk-integrated absorption lines isolating stellar granulation for high-precision RV studies
Ginger Frame, Heather Cegla, Cis Lagae +6
We present a novel method for constructing high-accuracy, time-varying disk-integrated stellar absorption line profiles that isolate the effects of granulation alone. This framewor…
Towards understanding stellar variability at the sub m/s level: Isolating granulation signals in synthetic spectral lines
Ginger Frame, Heather M. Cegla, Veronika Witzke +5
Granulation in the photospheres of FGK-type stars induces variability in absorption lines, complicating exoplanet detection via radial velocities and characterisation via transmiss…
TOI-2498 b: A hot bloated super-Neptune within the Neptune desert
Ginger Frame, David J. Armstrong, Heather M. Cegla +39
We present the discovery and confirmation of a transiting hot, bloated Super-Neptune using photometry from TESS and LCOGT and radial velocity measurements from HARPS. The host star…
