The Star-Planet Activity Research CubeSat (SPARCS): Determining Inputs to Planetary Habitability

David R. Ardila, Evgenya Shkolnik, Paul Scowen +19

Seventy-five billion low-mass stars in our galaxy host at least one small planet in their habitable zone (HZ). The stellar ultraviolet (UV) radiation received by the planets is str…

Time-Resolved Photometry of the High-Energy Radiation of M Dwarfs with the Star-Planet Activity Research CubeSat (SPARCS)

Tahina Ramiaramanantsoa, Judd D. Bowman, Evgenya L. Shkolnik +18

Know thy star, know thy planet,... especially in the ultraviolet (UV). Over the past decade, that motto has grown from mere wish to necessity in the M dwarf regime, given that the…

Space Photometry with BRITE-Constellation

Weiss W. W, Zwintz K., Kuschnig R. +16

BRITE-Constellation is devoted to high-precision optical photometric monitoring of bright stars, distributed all over the Milky Way, in red and/or blue passbands. Photometry from s…

Correlated X-ray and optical variability in the O-type supergiant zeta Puppis

Joy S. Nichols, Yael Naze, David P. Huenemoerder +11

Analysis of the recent long exposure Chandra X-ray observation of the early-type O star zeta Pup shows clear variability with a period previously reported in optical photometric st…

The chaotic wind of WR 40 as probed by BRITE

Tahina Ramiaramanantsoa, Richard Ignace, Anthony F. J. Moffat +9

Among Wolf-Rayet stars, those of subtype WN8 are the intrinsically most variable. We have explored the long-term photometric variability of the brightest known WN8 star, WR 40, thr…

A BRITE view on the massive O-type supergiant V973 Scorpii: Hints towards internal gravity waves or subsurface convection zones

Tahina Ramiaramanantsoa, Rathish Ratnasingam, Tomer Shenar +9

Stochastically-triggered photospheric light variations reaching mmag peak-to-valley amplitudes have been detected in the O8Iaf supergiant V973 Scorpii as the outcome of…
