The Planet Formation Potential Around a 45 Myr old Accreting M Dwarf
Kevin M. Flaherty, A. Meredith Hughes, Eric E. Mamajek +1
Debris disk detections around M dwarfs are rare, and so far no gas emission has been detected from an M dwarf debris disk. This makes the 45 Myr old M dwarf WISEJ080822.18-644357.3…
Super-Nyquist Asteroseismology with Future Space Missions
Hiromoto Shibahashi, Simon J. Murphy
We propose a photometric technique for future space missions that overcomes the problem of Nyquist aliases. These aliases result from typically long cadences of observation imposed…
Detection of a giant flare displaying quasi-periodic pulsations from a pre-main sequence M star with NGTS
James A. G. Jackman, Peter J. Wheatley, Chloe E. Pugh +18
We present the detection of an energetic flare on the pre-main sequence M3 star NGTS J121939.5-355557, which we estimate as only 2 Myr old. The flare had an energy of $3.2\pm^{0.4}…
Pulsating stars in binary systems: a review
Simon J. Murphy
Binary systems anchor many of the fundamental relations relied upon in asteroseismology. Masses and radii are rarely constrained better than when measured via orbital dynamics and…
Period spacings of Doradus pulsators in the Kepler field: detection methods and application to 22 slow rotators
Gang Li, Timothy R. Bedding, Simon J. Murphy +3
In Doradus stars, the g-mode period spacing shows an approximately linear relation with period. The slope is a new asteroseismic diagnostic, related to the rotation rate and th…
A window into Sct stellar interiors: Understanding the eclipsing binary system TT Hor
Margaret Streamer, Michael J. Ireland, Simon J. Murphy +1
The semi-detached eclipsing binary system, TT Hor, has a Sct primary component (accretor) accreting mass from the secondary star (donor). We fit an eclipsing binary model from…
