High five from ASTEP: Three validated planets and two eclipsing binaries in a diverse set of long-period candidates

Erika Rea, Maximilian N. Günther, George Dransfield +44

We present the analysis of five long-period TESS Objects of Interest (TOIs), all orbiting Sun-like stars, with orbital periods exceeding one month. Initially identified by the Tran…

The TESS All-Sky Rotation Survey: Periods for 1,046,317 Stars Within 500 pc

Andrew W. Boyle, Luke G. Bouma, Andrew W. Mann

Stellar rotation is a fundamental tracer of stellar magnetic evolution, age, and activity, with broad implications for Galactic archaeology and exoplanet characterization. The Tran…

Dust cloud lifetimes of Scallop-shell stars

Simon Daley-Yates, Moira M. Jardine, Luke Bouma

We investigate the survival of dust trapped in magnetically confined cool gas clouds (or {\it prominences}) around rapidly rotating M-dwarfs exhibiting the ``scallop-shell'' light-…

The T16 Planet Hunt: 10,000 New Planet Candidates from TESS Cycle 1 and the Confirmation of a Hot Jupiter Around TIC 183374187

Joshua T. Roth, Joel D. Hartman, Gáspár Á. Bakos +12

The T16 project has produced a uniformly detrended and systematics-corrected set of 83,717,159 TESS Cycle 1 full-frame image light curves for stars observed by TESS in its primary…

Lost Sisters Found: TESS and Gaia Reveal a Dissolving Pleiades Complex

Andrew W. Boyle, Luke G. Bouma, Andrew W. Mann

Most star clusters dissolve into the Galaxy over tens to hundreds of millions of years after they form. While recent Gaia studies have honed our view of cluster dispersal, the exac…

The HD 60779 Planetary System: A Transiting Sub-Neptune on a 30-day Orbit and a More Massive Outer World

Victoria DiTomasso, David Charbonneau, Andrew Vanderburg +37

We present the discovery of the planetary system orbiting the bright (V = 7.2), nearby (35 pc), Sun-like star HD 60779, which has a mass of 1.050 +/- 0.044 solar masses and a radiu…
