The metallicity–period–mass diagram of low-mass exoplanets [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
The number of exoplanet detections continues to grow following the development of better instruments and missions. Key steps for the understanding of these worlds comes from their characterization and its statistical studies. We explore the metallicity-period-mass diagram for known exoplanets by using an updated version of The Stellar parameters for ...

Deep inside low-mass stars [PDF]

open access: yes, 2008
Low-mass stars exhibit, at all stages of their evolution, the signatures of complex physical processes that require challenging modeling beyond standard stellar theory.

Coronae of Zero/Low-metal, Low-mass Stars [PDF]

open access: yesThe Astrophysical Journal, 2019
Abstract Recent theoretical studies suggest the existence of low-mass, zero-metal stars in the current universe. To study the basic properties of the atmosphere of low-mass first stars, we perform one-dimensional magnetohydrodynamical simulations for the heating of coronal loops on low-mass stars with various metallicities.

OGLE-2018-BLG-1185b: A Low-mass Microlensing Planet Orbiting a Low-mass Dwarf [PDF]

open access: yesThe Astronomical Journal, 2021
Abstract We report an analysis of the planetary microlensing event OGLE-2018-BLG-1185, which was observed by a large number of ground-based telescopes and by the Spitzer Space Telescope. The ground-based light curve indicates a low planet–host star mass ratio of q = (6.9 ± 0.2) × 10−5, which is near the peak of the wide-orbit exoplanet ...

Large mass, low temperature, low background detectors

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1992
Abstract Bolometric detectors can be realized with a wide range of materials, and large mass. Some aspects regarding the energy resolution of large bolometers are analyzed. Preliminary experimental results on neutrinoless ββ decay of tellurium, obtained with this technique, are shown.

Eliminating the low-mass axigluon window [PDF]

open access: yes, 1998
Using recent collider data, especially on the hadronic width the Z0, we exclude axigluons in the currently allowed low-mass window, namely axigluons in the mass range 50 GeV < M_A < 120 GeV.

The influence of metallurgical state of substrate on the efficiency of plasma electrolytic oxidation (PEO) process on magnesium alloy

open access: yesMaterials & Design, 2019
A Gd,Y rare-earth containing magnesium alloy (content in weight %, 10 Gd, 3 Y, 0.4 Zr and Mg as balance) is PEO processed for three different metallurgical states: (i) as-extruded, (ii) T4 solution (2 h at 500 °C) and (iii) T6 peak-aged precipitation (2 ...

Low-Mass Versus High-Mass Star Formation [PDF]

open access: yesSymposium - International Astronomical Union, 1997
Structures like the clumps identified in the CO maps of the Rosette Molecular Cloud and the dense cores such as those in B5, a cluster of cores and young low-mass stars, are key to considerations of star formation. Whether star formation is a self-inducing process or one that causes itself to turn off depends greatly on whether the responses of the ...

Suppression of phase transitions and glass phase signatures in mixed cation halide perovskites

open access: yesNature Communications, 2020
Understanding the underlying physics and improving the performance of mixed lead halide perovskite materials remains a challenge. Here, the authors present experimental and theoretical study of structural phases, phase transitions, and dipolar dynamics ...

Low-mass Quiescent Galaxies Are Small in Isolated Environments: Environmental Dependence of the Mass–Size Relation of Low-mass Quiescent Galaxies

open access: yesThe Astrophysical Journal, 2023
We study the mass–size relation of quiescent galaxies across various environments, with a particular focus on its environmental dependence at the low-mass part of $\mathrm{log}({M}_{\mathrm{star}}/{M}_{\odot })\lesssim 10.0$ .
