Polarization position angle standard stars: a reassessment of and its variability for seventeen stars based on a decade of observations
Daniel V. Cotton, Jeremy Bailey, Lucyna Kedziora-Chudczer +14
Observations of polarization position angle () standards made from 2014 to 2023 with the High Precision Polarimetric Instrument (HIPPI) and other HIPPI-class polarimeters in bot…
Polarimetric detection of nonradial oscillation modes in the beta Cephei star beta Crucis
Daniel V. Cotton, Derek L. Buzasi, Conny Aerts +11
Here we report the detection of polarization variations due to nonradial modes in the beta Cephei star beta Crucis. In so doing we confirm 40-year-old predictions of pulsation-indu…
The wavelength dependence of interstellar polarization in the Local Hot Bubble
Daniel V. Cotton, Jonathan P. Marshall, Priscilla C. Frisch +6
The properties of dust in the interstellar medium (ISM) nearest the Sun are poorly understood because the low column densities of dust toward nearby stars induce little photometric…
The Rotationally Modulated Polarization of Boo A
Daniel V. Cotton, Dag Evensberget, Stephen C. Marsden +9
We have observed the active star Boo A (HD 131156A) with high precision broadband linear polarimetry contemporaneously with circular spectropolarimetry. We find both signals ar…
Polarization due to rotational distortion in the bright star Regulus
Daniel V. Cotton, Jeremy Bailey, Ian D. Howarth +4
Polarization in stars was first predicted by Chandrasekhar [1] who calculated a substantial linear polarization at the stellar limb for a pure electron-scattering atmosphere. This…
Carrying a Torch for Dust in Binary Star Systems
Daniel V. Cotton, Jonathan P. Marshall, Kimberly Bott +2
Young stars are frequently observed to host circumstellar disks, within which their attendant planetary systems are formed. Scattered light imaging of these proto-planetary disks r…
