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 functions.

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 empirical mass-luminosity relation for low mass stars [PDF]

open access: yesAstrophysics and Space Science, 2008
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-negligible errors in all coordinates with different dimensions.

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.

Benchmark low-mass objects in Moving Groups [PDF]

open access: yesEPJ Web of Conferences, 2013
In order to compile a sample of ultracool dwarfs that will serve as benchmarks for testing theoretical formation and evolutionary models, we selected low-mass cool (>M7) objects that are potentially members of five known young Moving Groups in the solar ...

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 ...

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 ...
