Capture into Apsidal Resonance and the Decimation of Planets around In-spiraling Binaries
Mohammad Farhat, Jihad Touma
Transiting circumbinary planets (CBPs) are conspicuously rare, and entirely absent around stellar binaries with periods days. Here, we exploit a secular resonance to stimu…
Networked Infectiousness: Cascades, Power Laws, and Kinetics
Sara Najem, Leonid Klushin, Jihad Touma
Networked SIR models have become essential workhorses in the modeling of epidemics, their inception, propagation and control. Here, and building on this venerable tradition, we rep…
The case of HD 106906 debris disc: A binary's revenge
Mohammad Farhat, Antranik Sefilian, Jihad Touma
Debris disc architecture presents [exo-]planetary scientists with precious clues for processes of planet formation and evolution, including constraints on planetary mass perturbers…
A Framework for Reconstructing COVID-19 Transmission Network to Inform Betweenness Centrality-Based Control Measures
Sara Najem, Stefano Monni, Rola Hatoum +6
In this paper, we propose a general framework for optimal control measures, which follows the evolution of COVID-19 infection counts collected by Surveillance Units on a country le…
Laplace surface dynamics, revisited: satellites, exo-planets and debris with distant, eccentric companions
Mohammad Farhat, Jihad Touma
To date, studies of dynamics have concerned themselves with test particle orbits of fixed shape and orientation in the combined field of an oblate centra…
An order-disorder phase transition in black-hole star clusters
Jihad Touma, Scott Tremaine, Mher Kazandjian
The centers of most galaxies contain massive black holes surrounded by dense star clusters. The structure of these clusters determines the rate and properties of observable transie…
