An Updated Mass–Radius Analysis of the 2017–2018 NICER Data Set of PSR J0030+0451 [PDF]
Astrophysical Journal, 2023 In 2019 the NICER collaboration published the first mass and radius inferred for PSR J0030+0451, thanks to NICER observations, and consequent constraints on the equation of state characterizing dense matter.

The Radius of PSR J0740+6620 from NICER and XMM-Newton Data [PDF]
Astrophysical Journal Letters, 2021 PSR J0740+6620 has a gravitational mass of 2.08 ± 0.07 M ⊙, which is the highest reliably determined mass of any neutron star. As a result, a measurement of its radius will provide unique insight into the properties of neutron star core matter at high ...

Constraints on the Dense Matter Equation of State and Neutron Star Properties from NICER’s Mass–Radius Estimate of PSR J0740+6620 and Multimessenger Observations [PDF]
Astrophysical Journal Letters, 2021 In recent years our understanding of the dense matter equation of state (EOS) of neutron stars has significantly improved by analyzing multimessenger data from radio/X-ray pulsars, gravitational wave events, and from nuclear physics constraints.

Density, not radius, separates rocky and water-rich small planets orbiting M dwarf stars [PDF]
Science, 2022 Exoplanets smaller than Neptune are common around red dwarf stars (M dwarfs), with those that transit their host star constituting the bulk of known temperate worlds amenable for atmospheric characterization.

Structural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023 Considering that the effect of solar radiation on the super‐high arch dam temperature field remains poorly studied, the calculation accuracy of dam temperature deformation is unable to be guaranteed accordingly. To address the issue, the solar radiation effect is adequately taken into consideration by proposing a practical calculation method based on ...

The spectral radius of graphs with no odd wheels [PDF]
European journal of combinatorics (Print), 2021 The odd wheel W 2 k + 1 is the graph formed by joining a vertex to a cycle of length 2 k . In this paper, we investigate the largest value of the spectral radius of the adjacency matrix of an n -vertex graph that does not contain W 2 k + 1 . We determine

Role of A‐Site Composition in Charge Transport in Lead Iodide Perovskites
Advanced Energy and Sustainability Research, Volume 3, Issue 11, November 2022., 2022 The electronic properties of metal halide perovskites are measured with time‐resolved microwave conductivity, as a function of A‐site composition. It is found that a small percentage of Cs leads to a larger carrier mobility and lifetime and that compositions with a tolerance factor close to 0.9 generally show lower performance than those closer to 0.8 ...

Dynamical Characterization of the Loop Current Attractor
Geophysical Research Letters, Volume 48, Issue 24, 28 December 2021., 2021 Abstract The Gulf of Mexico circulation is modulated by a mesoscale current, the Loop Current (LC), and large anticyclonic eddies that detach from it. The LC dynamics are recurrent, and its evolution is in and from a few preferential states. This observation points to the existence of a low‐dimensional dynamical attractor. Building upon advancements in

Mass–Radius Relationships for Irradiated Ocean Planets [PDF]
Astrophysical Journal, 2021 Massive and water-rich planets should be ubiquitous in the universe. Many of these worlds are expected to be subject to important irradiation from their host star, and display supercritical water layers surrounded by extended steam atmospheres ...
