The orbital period and inclination of the neutron star X-ray transient MAXI J1807+132
The neutron star X-ray transient MAXI J1807+132 has undergone outbursts in 2017, 2019, and 2023. We conducted an $R$-band time series photometry campaign using the Isaac Newton Telescope during the 2022 quiescent state. We detected a periodic variation in the light curve, consistent with ellipsoidal modulation, which allowed us to determine an orbital period of $P_{\rm orb} = 4.258 \pm 0.008$ hr. By modelling the light curve, we obtained a binary inclination of $ i = 72\pm5 \, °$ and a mass ra…

Efficient Long-Time Simulations of Multiscale Systems via High-Order Numerical Homogenization
By a high-order numerical homogenization method, a heterogeneous multiscale scheme was developed in Jin & Li (2022) for evolving differential equations containing two time scales. In this paper, we further explore the technique to propose an efficient algorithm able to carry out simulations up to a long time which was prohibitive before. The new algorithm is a multigrid-in-time method which combines coarse-grid high-order approximations with fine-grid low-order evaluations. The high efficiency …

Rhoda Dakar - "The Man Who Sold The World" (2022)
So many good versions of this song. This one has been in heavy rotation on my iTunes lately.
Such a jaunty, classy version by one of the great voices of the 2nd wave ska era. Still going strong.
