“…Fortunately, variants of the Baade-(Becker-) Wesselink (BW;Lindemann 1918;Baade 1926;Becker 1940;Wesselink 1946) technique afford a homogeneous methodology for determining individual geometric distances to Cepheids in the Galaxy, LMC, and SMC (e.g. Storm et al 2004;Groenewegen 2008;Storm et al 2011;Groenewegen 2013).…”

Baade-Wesselink-type (BW) techniques enable geometric distance measurements of Cepheid variable stars in the Galaxy and the Magellanic clouds. The leading uncertainties involved concern projection factors required to translate observed radial velocities (RVs) to pulsational velocities and recently discovered modulated variability.We carried out an unprecedented observational campaign involving long-baseline interferometry (VLTI/PIONIER) and spectroscopy (Euler/Coralie) to search for modulated variability in the long-period (P ∼ 35.5 d) Cepheid Carinae. We determine highly precise angular diameters from squared visibilities and investigate possible differences between two consecutive maximal diameters, ∆ max Θ. We characterize the modulated variability along the line-of-sight using 360 high-precision RVs.Here we report tentative evidence for modulated angular variability and confirm cycleto-cycle differences of Carinae's RV variability. Two successive maxima yield ∆ max Θ = 13.1 ± 0.7(stat.) µas for uniform disk models and 22.5 ± 1.4(stat.) µas (4% of the total angular variation) for limb darkened models. By comparing new RVs with 2014 RVs we show modulation to vary in strength. Barring confirmation, our results suggest the optical continuum (traced by interferometry) to be differently affected by modulation than gas motions (traced by spectroscopy). This implies a previously unknown time-dependence of projection factors, which can vary by 5% between consecutive cycles of expansion and contraction.Additional interferometric data are required to confirm modulated angular diameter variations. By understanding the origin of modulated variability and monitoring its long-term behavior, we aim to improve the accuracy of BW distances and further the understanding of stellar pulsations.

Eclipsed among the millions of critical words that have been lavished on Samuel Beckett is an uncomfortable and frequently avoided question: on what level can spectators be expected to understand his theater? Some critics have tried to address this issue by pointing out parallels between the dilemmas of Beckett's characters and those of his audiences, with limited success, but I want to shift the field of inquiry by discussing affinities between the actor's process of creating characters in rehearsal and the spectator's process of apprehending plays in performance. I focus predominantly on Rockaby, because Billie Whitelaw's extraordinary performance is well documented and also because there is an important article by Charles Lyons about the process of perceiving this play. Lyons's essay, which has application to Beckett 's other works as well, is to my knowledge unique in its detail concerning perception, yet strangely it does not mention Whitelaw at all despite the fact that her kind of acting figures hugely in the process described.
