Exploring the directly imaged HD 1160 system through spectroscopic characterization and high-cadence variability monitoring
Ben J. Sutlieff, Jayne L. Birkby, Jordan M. Stone +15
The time variability and spectra of directly imaged companions provide insight into their physical properties and atmospheric dynamics. We present follow-up R~40 spectrophotometric…
Detection of polarization neutral points in observations of the combined corona and sky during the 21 August 2017 total solar eclipse
Frans Snik, Steven P. Bos, Stefanie A. Brackenhoff +7
We report the results of polarimetric observations of the total solar eclipse of 21 August 2017 from Rexburg, Idaho (USA). We use three synchronized DSLR cameras with polarization…
First Images of the Protoplanetary Disk Around PDS 201
Kevin Wagner, Jordan Stone, Ruobing Dong +11
Scattered light imaging has revealed nearly a dozen circumstellar disks around young Herbig Ae/Be starsenabling studies of structures in the upper disk layers as potential signs…
Discovery of a directly imaged disk in scattered light around the Sco-Cen member Wray 15-788
A. J. Bohn, M. A. Kenworthy, C. Ginski +10
As part of our on-going survey we have carried out high-contrast imaging with VLT/SPHERE/IRDIS to obtain polarized and total intensity images of the young (Myr old)…
Magnetic field topology and chemical spot distributions in the extreme Ap star HD 75049
O. Kochukhov, N. Rusomarov, J. A. Valenti +7
Intermediate-mass, magnetic chemically peculiar (Ap) stars provide a unique opportunity to study the topology of stellar magnetic fields in detail and to investigate magnetically d…
Three-dimensional magnetic and abundance mapping of the cool Ap star HD 24712 I. Spectropolarimetric observations in all four Stokes parameters
N. Rusomarov, O. Kochukhov, N. Piskunov +8
High-resolution spectropolarimetric observations provide simultaneous information about stellar magnetic field topologies and three-dimensional distributions of chemical elements.…
