Spectropolarimetry of single and binary stars [PDF]
, 2005 Spectropolarimetry is a photon-hungry technique that will reach fruition in the 8-m telescope age. Here I summarize some of the stellar spectropolarimetric research that my collaborators and I have undertaken, with particular emphasis on the ...

Advanced Science, Volume 10, Issue 29, October 17, 2023., 2023 This study focuses on the molecular action of two histone chaperones: SET/template‐activating factor‐Iβ and nucleophosmin 1. It is shown how these chaperones have specificity for fully dismantled nucleosomes, characterized the histone eviction (removal) process, and its modulation by cytochrome c.

Early Time Spectropolarimetry of the Aspherical Type II Supernova SN 2023ixf
The Astrophysical Journal Letters, 2023 We present six epochs of optical spectropolarimetry of the Type II supernova (SN) 2023ixf ranging from ∼2 to 15 days after the explosion. Polarimetry was obtained with the Kast double spectrograph on the Shane 3 m telescope at Lick Observatory ...

Channeled spectropolarimetry using a coherent white-light continuum [PDF]
, 2010 We carry out polarization measurements using a coherent white-light continuum as a light source for channeled spectropolarimetry. The white-light continuum, whose spectrum ranges from the UV to the IR region, is generated in Kr gas by a terawatt ...

Core Collapse Supernovae - 35 Years of Spectropolarimetry
, 2022 I will give a brief of overview of what spectropolarimetry has taught us about core collapse supernovae and stripped envelope supernovae, as well as highlight what I see as being the main challenges/issues that now need to be addressed to take us to the ...

Asteroseismology and Spectropolarimetry of the Exoplanet Host Star λ Serpentis
The Astronomical Journal, 2023 The bright star λ Ser hosts a hot Neptune with a minimum mass of 13.6 M _⊕ and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 days and surface differential rotation very similar to the Sun.

Optical Spectropolarimetry of Binary Asteroid Didymos–Dimorphos before and after the DART Impact
The Astrophysical Journal Letters, 2023 We have monitored the Didymos–Dimorphos binary asteroid in spectropolarimetric mode in the optical range before and after the DART impact. The ultimate goal was to obtain constraints on the characteristics of the ejected dust for modeling purposes ...
