Predicting the long-term stability of compact multiplanet systems

Posted by klaurent Tokyo

Kavli Affiliate: David Spergel | First 5 Authors: Daniel Tamayo, Miles Cranmer, Samuel Hadden, Hanno Rein, Peter Battaglia | Summary: We combine analytical understanding of resonant dynamics in two-planet systems with machine learning techniques to train a model capable of robustly classifying stability in compact multi-planet systems over long timescales of $10^9$ orbits. Our Stability […]

Plasma Diagnostics of the Supernova Remnant N132D Using Deep XMM-Newton Observations with the Reflection Grating Spectrometer

Posted by klaurent MIT

Kavli Affiliate: Eric D. Miller | First 5 Authors: Hitomi Suzuki, Hiroya Yamaguchi, Manabu Ishida, Hiroyuki Uchida, Paul P. Plucinsky | Summary: We present XMM-Newton observations of N132D, the X-ray brightest supernova remnant (SNR) in the Large Magellanic Cloud (LMC), using the Reflection Grating Spectrometer (RGS) that enables high-resolution spectroscopy in the soft X-ray band. […]
