Extended Data Fig. 6: Optical photometry performed by ANS 1, 3, and 4 days after the outburst.
From: Proton acceleration in thermonuclear nova explosions revealed by gamma rays
Optical photometry performed by ANS 1, 3, and 4 days (see the panel titles) after the outburst (blue empty markers) corrected for the Galactic absorption. Filled markers show the flux after subtraction of Hα and Hß line contributions. The thick black lines show a black-body emission used in the modeling, while the dashed line shows for comparison the average 2006 spectral fit from [52] (with the photosphere radius corrected to the distance of 2.45 kpc). Horizontal error bars represent the bandwidth of the filters used.
