A SUPER-EARTH TRANSITING A NAKED-EYE STAR*
- J. Winn, J. Matthews, +11 authors W. Weiss
- Physics
- 27 April 2011
We have detected transits of the innermost planet 'e' orbiting 55 Cnc (V = 6.0), based on two weeks of nearly continuous photometric monitoring with the MOST space telescope. The transits occur with… Expand
MOST space-based photometry of the transiting exoplanet system HD 189733: precise timing measurements for transits across an active star
- E. Miller-Ricci, J. Rowe, +8 authors W. Weiss
- Physics
- 19 February 2008
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 this… Expand
Echography of young stars reveals their evolution
- K. Zwintz, L. Fossati, +17 authors W. Weiss

- Science
- 18 July 2014
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 the… Expand
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 of… Expand
TT Arietis -- observations of a Cataclysmic Variable Star with the MOST Space Telescope
- J. Weingrill, G. Kleinschuster, +5 authors W. Weiss
- Physics
- 23 June 2009
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 other… Expand
The first view of δ Scuti and γ Doradus stars with the TESS mission
- V. Antoci, M. Cunha, +47 authors P. Lampens
- 2019
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 to… Expand

Pulsations Beneath the Winds: Unique Precise Photometry from MOST
- A. Moffat, S. Marchenko, +14 authors W. Weiss
- Physics
- 1 June 2008
It has now been three years since the first Canadian space telescope MOST (Microvariability and Oscillations of STars) continues to make its unique mark in stellar asteroseismology, exoplanetology… Expand

Constraining the Evolution of ZZ Ceti
- A. Mukadam, S. O. Kepler, +63 authors T. K. Watson
- Physics
- 2003
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
- T. Kallinger, D. Günther, +8 authors D. Sasselov
- Physics
- 1 April 2008
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 nearly… Expand
