Optimized temporal binning of comparison star measurements for differential photometry (2023)
Journal Article
Hartley, K. E., & Wilson, R. W. (2023). Optimized temporal binning of comparison star measurements for differential photometry. Monthly Notices of the Royal Astronomical Society, 526(3), 3482-3494. https://doi.org/10.1093/mnras/stad2964

Ground-based, high precision observations of the light curves of objects such as transiting exoplanets rely on the application of differential photometry. The flux of the target object is measured relative to a comparison star in the same field, allo...

Optical sparse telescope arrays and scintillation noise (2023)
Journal Article
Hartley, K. E., Farley, O. J. D., Townson, M. J., Osborn, J., & Wilson, R. W. (2023). Optical sparse telescope arrays and scintillation noise. Monthly Notices of the Royal Astronomical Society, 526(1), 1235-1245. https://doi.org/10.1093/mnras/stad2835

Fresnel propagation of starlight after it passes through high altitude turbulence in the Earth’s atmosphere results in random fluctuations of the intensity at ground level, known as scintillation. This effect adds random noise to photometric measurem... Read More about Optical sparse telescope arrays and scintillation noise.

First On-Sky Demonstration of a Scintillation Correction technique using Tomographic Wavefront Sensing (2023)
Journal Article
Hartley, K. E., Farley, O. J., Townson, M. J., Osborn, J., & Wilson, R. (2023). First On-Sky Demonstration of a Scintillation Correction technique using Tomographic Wavefront Sensing. Monthly Notices of the Royal Astronomical Society, 520(3), 4134-4146. https://doi.org/10.1093/mnras/stad420

Scintillation noise significantly limits high precision ground-based photometry of bright stars. In this paper we present the first ever on-sky demonstration of scintillation correction. The technique uses tomographic wavefront sensing to estimate th... Read More about First On-Sky Demonstration of a Scintillation Correction technique using Tomographic Wavefront Sensing.
