A Long Spin Period for a Sub-Neptune-mass Exoplanet

HIP 41378 f is a sub-Neptune exoplanet with an anomalously low density. Its long orbital period and deep transit make it an ideal candidate for detecting oblateness photometrically. We present a new cross-platform, GPU-enabled code, greenlantern , suitable for computing transit light curves of oblat...
