Extreme precision photometry from the ground with beam-shaping diffusers for K2, TESS and beyond
Gudmundur Stefansson, Suvrath Mahadevan, John Wisniewski +7
The Transiting Exoplanet Survey Satellite (TESS, launched early 2018) is expected to find a multitude of new transiting planet candidates around the nearest and brightest stars. Ti…
Diffuser-assisted Photometric Follow-up Observations of the Neptune-sized Planets K2-28b and K2-100b
Gudmundur Stefansson, Yiting Li, Suvrath Mahadevan +5
We present precision transit observations of the Neptune-sized planets K2-28b and K2-100b, using the Engineered Diffuser on the ARCTIC imager on the ARC 3.5m Telescope at Apache Po…
A Candidate Transit Event around Proxima Centauri
Yiting Li, Gudmundur Stefansson, Paul Robertson +3
We present a single candidate transit event around Proxima Centauri, found during a blind transit search using a robotic 30\,cm telescope at Las Campanas Observatory. The event las…
Towards Space-like Photometric Precision from the Ground with Beam-Shaping Diffusers
Gudmundur Stefansson, Suvrath Mahadevan, Leslie Hebb +21
We demonstrate a path to hitherto unachievable differential photometric precisions from the ground, both in the optical and near-infrared (NIR), using custom-fabricated beam-shapin…
