The Dual-Axis Circumstellar Environment of the Type IIn Supernova 1997eg (2007)
Hoffman, Jennifer L., Leonard, Douglas C., Chornock, Ryan, Filippenko, Alexei V., Barth, Aaron J., Matheson, Thomas
We present multi-epoch spectral and spectropolarimetric observations of the Type IIn supernova (SN) 1997eg that indicate the presence of a flattened disk-like concentration of circumstellar material...
Supernova Polarization and the Type IIn Classification (2007)
While the members of the Type IIn category of supernovae are united by the presence of strong multicomponent Balmer emission lines in their spectra, they are quite heterogeneous with respect to other...
Polarized Line Profiles as Diagnostics of Circumstellar Geometry in Type IIn Supernovae (2006)
Supernovae of type IIn possess spectral signatures that indicate an intense interaction between the supernova ejecta and surrounding dense circumstellar material cast off by the star in pre-explosion...

Leonard, Douglas C., Filippenko, Alexei V., Ganeshalingam, Mohan, Serduke, Franklin J. D., Li, Weidong, Swift, Brandon J., ...
An important and perhaps critical clue to the mechanism driving the explosion of massive stars as supernovae is provided by the accumulating evidence for asymmetry in the explosion. Indirect evidence...
The Orbit and Occultations of KH 15D (2006)
Winn, Joshua N., Hamilton, Catrina M., Herbst, William J., Hoffman, Jennifer L., Holman, Matthew J., Johnson, John A., ...
The unusual flux variations of the pre-main-sequence binary star KH 15D have been attributed to occultations by a circumbinary disk. We test whether or not this theory is compatible with newly...
