MOST space-based photometry of the transiting exoplanet system HD 189733: precise timing measurements for transits across an active star
We have measured transit times for HD 189733b passing in front of its bright (V = 7.67), chromospherically active, and spotted parent star. Nearly continuous broadband optical photometry of thisExpand

Echography of young stars reveals their evolution
A finger on the pulse of young stars Adolescent stars quiver and quake before the onset of nuclear fusion in their cores. Zwintz et al. confirm theoretical predictions that the frequency of theExpand

Detection of solar-like oscillations in the bright red giant stars γ Piscium and θ1 Tauri from a 190-day high-precision spectroscopic multi-site campaign⋆
Context. Red giants are evolved stars which exhibit solar-like oscil lations. Although a multitude of stars have been observed with space telescopes, only a handful of red-giant stars were targets ofExpand

TT Arietis -- observations of a Cataclysmic Variable Star with the MOST Space Telescope
We measured the photometric flux of the cataclysmic variable TT Arietis (BD+14 341) using the MOST space telescope. Periodic oscillations of the flux reveal the photometric period as well as otherExpand

The first view of δ Scuti and γ Doradus stars with the TESS mission
We present the first asteroseismic results for δ Scuti and γ Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilize the 2-min cadence TESS data for a sample of 117 stars toExpand

Constraining the Evolution of ZZ Ceti
Abstract We report our analysis of the stability of pulsation periods in the DAV star (pulsating hydrogen atmosphere white dwarf) ZZ Ceti, also called R548. Based on observations that span 31 years,Expand

MOST found evidence for solar-type oscillations in the K2 giant star HD 20884
Abstract We found evidence for radial p-modes and nonradial mixed modes in the oscilla-tion spectrum of the K giant HD20884 based on 20.6 days of nearlyExpand
