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 seconds – minutes pulsations associated with the convective eddy turnover timescale within the nova envelope .
We do not detect any periodic signal with greater than 3 \sigma significance .
Through injection and recovery , we rule out periodic signals of fractional amplitude > 7.08 \times 10 ^ { -4 } on timescales of 2 seconds and fractional amplitude > 1.06 \times 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 .
