Oscillation frequencies and mode lifetimes in alpha Centauri A
Timothy R. Bedding, Hans Kjeldsen, R. Paul Butler +5
We analyse our recently-published velocity measurements of alpha Cen A (Butler et al. 2004). After adjusting the weights on a night-by-night basis in order to optimize the window f…
RVTESS I: Modeling Asteroseismic Signals with Simultaneous Photometry and RVs
Jiaxin Tang, Sharon X. Wang, Yaguang Li +22
Detecting small planets via the radial velocity method remains challenged by signals induced by stellar variability, versus the effects of the planet(s). Here, we explore using Gau…
The Deeper, Wider, Faster programme's first DECam optical data release
James Freeburn, Jeff Cooke, Anais Möller +17
The transient and variable optical sky is relatively poorly characterised on fast (1hr) timescales. With the Dark Energy Camera (DECam), the Deeper, Wider, Faster programme…
Two Earth-size Planets and an Earth-size Candidate Transiting the Nearby Star HD 101581
Michelle Kunimoto, Zifan Lin, Sarah Millholland +43
We report the validation of multiple planets transiting the nearby ( pc) K5V dwarf HD 101581 (GJ 435, TOI-6276, TIC 397362481). The system consists of at least two Earth-…
