DOI: 10.1051/0004-6361/201936731
Abstract: We present a highly precise calculation of the theoretical light curve and its derivatives for a binary star-planet system in an elliptical orbit. We also describe an analytical fitting by limb-darkening coefficients to reduce the… read more here.

DOI: 10.1080/03736687.2017.1407280
Abstract: Diffusion theory predicts that, except in the lower part of the daylight range, carbon dioxide supply will always be limiting for photosynthesis in a unistratose leaf. We have used chlorophyll fluorometry to survey the photosynthetic… read more here.

DOI: 10.1093/mnras/staa2489
Abstract: A few fast radio bursts' (FRBs) light-curves have exhibited large intrinsic modulations of their flux on extremely short (t_r ∼ 10μs) time scales, compared to pulse durations (t_(FRB) ∼ 1ms). Light-curve variability timescales, the small… read more here.
