A discontinuity in the low-mass initial mass function [PDF]

open access: yesThe Astrophysical Journal, 2007
The origin of brown dwarfs (BDs) is still an unsolved mystery. While the standard model describes the formation of BDs and stars in a similar way recent data on the multiplicity properties of stars and BDs show them to have different binary distribution ...

Searches for low-mass dimuon resonances [PDF]

open access: yesJournal of High Energy Physics, 2020
Searches are performed for a low-mass dimuon resonance, X, produced in proton-proton collisions at a center-of-mass energy of 13 TeV, using a data sample corresponding to an integrated luminosity of 5.1 fb −1 and collected with the LHCb detector.

The Mass-Radius(-Rotation?) Relation for Low-Mass Stars [PDF]

open access: yesThe Astrophysical Journal, 2010
The fundamental properties of low-mass stars are not as well understood as those of their more massive counterparts. The best method for constraining these properties, especially masses and radii, is to study eclipsing binary systems, but only a small ...

Low bone mass in microscopic colitis [PDF]

open access: yesBMC Gastroenterology, 2011
Background Microscopic colitis presents with similar symptoms to classic inflammatory bowel diseases. Osteoporosis is a common complication of Crohn's disease but there are no data concerning bone metabolism in microscopic colitis.

The Empirical Mass-Luminosity Relation for Low Mass Stars [PDF]

open access: yesAstrophysics and Space Science, 2007
This work is devoted to improving empirical mass-luminosity relations and mass-metallicity-luminosity relation for low mass stars. For these stars, observational data in the mass-luminosity plane or the mass-metallicity-luminosity space subject to non ...

LOW-MASS DIFFRACTION AT THE LHC [PDF]

open access: yesModern Physics Letters A, 2011
The expected resonance structure for low-mass single diffractive states is predicted from a Regge-dual model elaborated earlier by the present authors. Estimates for the observable low-mass single diffraction dissociation (SDD) cross-sections and efficiencies for single diffractive events simulated by PYTHIA 6.2 as a function of the diffractive mass ...

Low-energy electron ionization mass spectrometer for efficient detection of low mass species [PDF]

open access: yesReview of Scientific Instruments, 2021
The design of a high-efficiency mass spectrometer is described, aimed at residual gas detection of low mass species using low-energy electron impact, with particular applications in helium atom microscopy and atomic or molecular scattering. The instrument consists of an extended ionization volume, where electrons emitted from a hot filament are ...

THE FREQUENCY OF LOW-MASS EXOPLANETS [PDF]

open access: yesThe Astrophysical Journal, 2009
We report first results from the Anglo-Australian Telescope Rocky Planet Search - an intensive, high-precision Doppler planet search targeting low-mass exoplanets in contiguous 48 night observing blocks. On this run we targeted 24 bright, nearby and intrinsically stable Sun-like stars selected from the Anglo-Australian Planet Search's main sample ...

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 ...
