Asteroseismic detection of a predominantly toroidal magnetic field in the deep interior of the main-sequence F star KIC 9244992
Masao Takata, Simon J. Murphy, Donald W. Kurtz +2
An asteroseismic analysis has revealed a magnetic field in the deep interior of a slowly-rotating main-sequence F star KIC9244992, which was observed by the Kepler spacecraft for f…
The orbital parameters of the binary BLAP HD133729 : advantages of the frequency modulation method
Hiromoto Shibahashi, Donald W. Kurtz, Simon J. Murphy
We derive all the orbital parameters of the blue large-amplitude pulsator (BLAP) in the binary system HD133729 by exploiting the frequency modulation (FM) method, which is based on…
On the first Sct--roAp hybrid pulsator and the stability of p and g modes in chemically peculiar A/F stars
Simon J. Murphy, Hideyuki Saio, Masahide Takada-Hidai +4
Strong magnetic fields in chemically peculiar A-type (Ap) stars typically suppress low-overtone pressure modes (p modes) but allow high-overtone p modes to be driven. KIC 11296437…
Pulsation in the white dwarf HE 1017-1352: confirmation of the class of hot DAV stars
Alejandra D. Romero, L. Antunes Amaral, S. O. Kepler +3
We report the detection of periodic variations on the T_eff ~32 000 K DA white dwarf star HE 1017-1352. We obtained time series photometry using the 4.1 m SOAR telescope on three s…
Search for quiet stellar-mass black holes by asteroseismology from space
Hiromoto Shibahashi, Simon J. Murphy
Stars with an initial mass more than ~25 Msun are thought to ultimately become black holes. Then stellar-mass black holes should be ubiquitous but fewer than 20 have been found in…
Asteroseismology as a new window to statistics of binaries
Hiromoto Shibahashi, Simon J. Murphy
More than 340 non-eclipsing binaries of A-F stars as primaries at intermediate periods (100-1000 d) were newly found by uninterrupted photometry with ultra high-precision taken ove…
