Machine-learning clustering of close-in exoplanet populations: links to pebble accretion

Astronomy & Astrophysics
Context. Close-in exoplanets span a wide range of orbital architectures and physical properties, consistent with the combined influence of migration processes and formation conditions.

The Principal Component Analysis Filtering Method for an Unbiased Spectral Survey of Complex Organic Molecules

The Astrophysical Journal, 2023
A variety of interstellar complex organic molecules (COMs) have been detected in various physical conditions. However, in the protostellar and protoplanetary environments, their complex kinematics make line profiles blend together and the line strength ...

Interstellar ices as carriers of supernova material to the early solar system

Nature Communications
Planetary materials show systematic variations in their nucleosynthetic isotope compositions that resonate with orbital distance. The origin of this pattern remains debated, limiting how these isotopic signatures can be used to trace the precursors of ...

Gas dynamics around dust asymmetries in turbulent disks

Astronomy & Astrophysics
High-resolution ALMA observations have revealed asymmetric dust crescents in several protoplanetary disks, suggesting efficient dust trapping mechanisms potentially linked to gas vortices.

A break in planet occurrence near the pebble isolation mass should be observable by the Roman microlensing survey

Astronomy & Astrophysics
Microlensing detections are uniquely well suited to probing the population of planets outside the water ice line, down to planetary masses comparable to the Earth’s. We performed 1D pebble-accretion population synthesis simulations to explore a sample of

The Effect of f(R, T) Modified Gravity on the Mass and Radius of Pulsar HerX1

The Astrophysical Journal, 2023
Millisecond pulsars are the perfect testable to examine potential matter-geometry coupling and its physical consequences in the context of the recent Neutron Star Interior Composition Explorer discoveries. We apply the field equations of modified gravity,

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...
