Rotation numbers and rotation classes on one-dimensional tiling spaces
José Aliste-Prieto, Betseygail Rand, Lorenzo Sadun
We extend rotation theory of circle maps to tiling spaces. Specifically, we consider a 1-dimensional tiling space with finite local complexity and study self-maps that are…
A 15.7-Minute AM CVn Binary Discovered in K2
M. J. Green, J. J. Hermes, T. R. Marsh +14
We present the discovery of SDSS J135154.46-064309.0, a short-period variable observed using 30-minute cadence photometry in K2 Campaign 6. Follow-up spectroscopy and high-speed ph…
Rapid Evolution of the Gaseous Exoplanetary Debris Around the White Dwarf Star HE 1349--2305
E. Dennihy, J. C. Clemens, B. H. Dunlap +3
Observations of heavy metal pollution in white dwarf stars indicate that metal-rich planetesimals are frequently scattered into star-grazing orbits, tidally disrupted, and accreted…
Destroying Aliases from the Ground and Space: Super-Nyquist ZZ Cetis in K2 Long Cadence Data
Keaton J. Bell, J. J. Hermes, Z. Vanderbosch +5
With typical periods of order 10 minutes, the pulsation signatures of ZZ Ceti variables (pulsating hydrogen-atmosphere white dwarf stars) are severely undersampled by long-cadence…
Drell-Yan Production at NNLL'+NNLO Matched to Parton Showers
Simone Alioli, Christian W. Bauer, Calvin Berggren +2
We present results for Drell-Yan production from the GENEVA Monte-Carlo framework. We combine the fully-differential NNLO calculation with higher-order resummation in the 0-jettine…
An Approximation Theorem for Maps Between Tiling Spaces
Betseygail Rand, Lorenzo Sadun
We show that every continuous map from one translationally finite tiling space to another can be approximated by a local map. If two local maps are homotopic, then the homotopy can…
