Abstract

Abstract We present high-speed optical observations of the nova ASASSN-17hx, taken both immediately after its discovery and close to its first peak in brightness, to search for second–minute pulsations associated with the convective eddy turnover timescale within the nova envelope. We do not detect any periodic signal with greater than 3σ significance. Through injection and recovery, we rule out periodic signals of fractional amplitude >7.08 × 10−4 on timescales of 2 s and fractional amplitude >1.06 × 10−3 on timescales of 10 minutes. Additional observations of novae are planned to further constrain ongoing simulations of the launch and propagation of nova winds.
