The MUSCLES treasury survey. V. FUV Flares on active and inactive M Dwarfs

ROP Loyd, K France, A Youngblood… - The Astrophysical …, 2018 - iopscience.iop.org
… For the COS and STIS UV data, we created light curves over a given bandpass using the
process described in Loyd & France (2014). In brief, this involves binning detector events within …

Constraining the physical properties of stellar coronal mass ejections with coronal dimming: application to far-ultraviolet data of ϵ Eridani

ROP Loyd, JP Mason, M Jin, EL Shkolnik… - The Astrophysical …, 2022 - iopscience.iop.org

Stellar flares from blended and neighbouring stars in Kepler short cadence observations

…, E Shkolnik, ROP Loyd - Monthly Notices of the …, 2021 - academic.oup.com
We present the results of a search for stellar flares from stars neighbouring the target sources
in the Kepler short cadence data. These flares have been discarded as contaminants in …

Extending optical flare models to the UV: results from comparing of TESS and GALEX flare observations for M Dwarfs

…, S Fleming, T Richey-Yowell, ROP Loyd - Monthly Notices of …, 2023 - academic.oup.com
… To detect white-light flares in the TESS observations, we first detrended the light curves
following a method similar to that used in Jackman, Shkolnik & Loyd (2021a). This method is …

Fluctuations and flares in the ultraviolet line emission of cool stars: Implications for exoplanet transit observations

ROP Loyd, K France - The Astrophysical Journal Supplement …, 2014 - iopscience.iop.org
Variations in stellar flux can potentially overwhelm the photometric signal of a transiting planet.
Such variability has not previously been well-characterized in the ultraviolet lines used to …

Square Kilometre Array Pathfinder (ASKAP), Atacama Large Millimeter/submillimeter Array (…

The Mouse that Squeaked: A small flare from Proxima Cen observed in the millimeter, optical, and soft X-ray with Chandra and ALMA

…, A Youngblood, T Barclay, ROP Loyd… - The Astrophysical …, 2022 - iopscience.iop.org
We present millimeter, optical, and soft X-ray observations of a stellar flare with an energy
squarely in the regime of typical X1 solar flares. The flare was observed from Proxima Cen on …

The Volatility of Far-Ultraviolet Radiation from Low-Mass Stars and Planetary Implications

ROP Loyd - 2017 - search.proquest.com
A low-mass star emits only 0.001-0.01% of its electromagnetic energy in the ultraviolet (100–1700
Å), yet the implications for planets are profound. Radiation at the short-wavelength …
