Description
We present the first detections by the NASA K2 mission of oscillations
in solar-type stars, using short-cadence data collected during K2
Campaign 1 (C1). We understand the asteroseismic detection thresholds
for C1-like levels of photometric performance, and we can detect
oscillations in subgiants having dominant oscillation frequencies around
1000 μHz. Changes to the operation of the fine-guidance sensors are
expected to give significant improvements in the high-frequency
performance from C3 onwards. A reduction in the excess high-frequency
noise by a factor of 2.5 in amplitude would bring main-sequence stars
with dominant oscillation frequencies as high as ≃2500 μHz into
play as potential asteroseismic targets for K2.

The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary
