The Lightspeed project: high-speed, ultra-low read noise imaging and polarimetry for the Magellan telescopes
Christopher Layden, Kevin Burdge, John J. Piotrowski +12
Lightspeed will be an ultra-fast (> kHz), ultra-low read noise, multicolor (ugriz + IR) imager for the 6.5 meter Magellan Clay telescope. In a single-channel configuration, Lightsp…
Observing a 542-day transiting giant with large TTVs: The 2025 transit of HIP 41378 f and new constraints on the outer system
Pietro Leonardi, Alexandre Santerne, Luca Borsato +27
Characterizing long-period transiting exoplanets is inherently challenging due to the rarity and long duration of transit events. Yet, these systems provide unique insights into pl…
proto-Lightspeed: a high-speed, ultra-low read noise imager on the Magellan Clay Telescope
Christopher Layden, Kevin Burdge, Gabor Furesz +9
proto-Lightspeed is a new instrument that has been commissioned on the Nasmyth East port of the Magellan Clay Telescope at Las Campanas Observatory to deliver high-speed optical im…
RV and TTV Measurements of Two Transiting Long-Period Giants around TOI-4600
Tong Hu, Zitao Lin, Sharon X. Wang +27
TOI-4600b and c, originally identified by the Transiting Exoplanet Survey Satellite (TESS) and reported by I. Mireles et al. (2023), are a rare pair of transiting long-period giant…
A Ground-Based Transit Observation of the Long-Period Extremely Low-Density Planet HIP 41378 f
Juliana GarcÃa-MejÃa, Zoë L. de Beurs, Patrick Tamburo +25
We present a ground-based transit detection of HIP 41378 f, a long-period ( days), extremely low-density ( g cm) giant exoplanet in a dynamically com…
An eclipsing 8.56 minute orbital period mass-transferring binary
Emma T. Chickles, Joheen Chakraborty, Kevin B. Burdge +34
We report the discovery of ATLAS J101342.5-451656.8 (hereafter ATLAS J1013-4516), an 8.56 minute orbital period mass transferring AM Canum Venaticorum binary with mean Gaia magnitu…
