Doppler Constraints on Planetary Companions to Nearby Sun-like Stars: An Archival Radial Velocity Survey of Southern Targets for Proposed NASA Direct Imaging Missions
Katherine Laliotis, Jennifer A. Burt, Eric E. Mamajek +22
Directly imaging temperate rocky planets orbiting nearby, Sun-like stars with a 6-m-class IR/O/UV space telescope, recently dubbed the Habitable Worlds Observatory, is a high prior…
A study of the F-giant star Scorpii A: a post-merger rapid rotator?
Fiona Lewis, Jeremy Bailey, Daniel V. Cotton +3
We report high-precision observations of the linear polarization of the F1III star Scorpii. The polarization has a wavelength dependence of the form expected for a rapid ro…
Polarization measurements of hot dust stars and the local interstellar medium
J. P. Marshall, D. V. Cotton, K. Bott +7
Debris discs are typically revealed through excess emission at infrared wavelengths. Most discs exhibit excess at mid- and far-infrared wavelengths, analogous to the solar system's…
On the Detection of Artefacts in Spectro-astrometry
E. Brannigan, M. Takami, A. Chrysostomou +1
We demonstrate that artificial bipolar structure can be detected using spectro-astrometry when the point spread function (PSF) of a point source suffers distortion in a relatively…
A spectro-astrometric study of southern pre-main sequence stars - binaries, outflows, and disc structure down to AU scales
Michihiro Takami, Jeremy Bailey, Antonio Chrysostomou
We present spectro-astrometric observations for 28 southern pre-main sequence (PMS) stars and investigate their circumstellar environment down to AU scales. The structures detected…
GRB 011121: A Massive Star Progenitor
P. A. Price, E. Berger, D. E. Reichart +29
Of the cosmological gamma-ray bursts, GRB 011121 has the lowest redshift, z=0.36. More importantly, the multi-color excess in the afterglow detected in the Hubble Space Telescope (…
