Massive luminous early type stars in the LMC [PDF]
Astronomy & Astrophysics, 2002 In order to construct a comprehensive HRD of early type stars in the Large Magellanic Cloud (LMC) in the first step the reddenings of individual stars and the LMC reddening law have been investigated. 1942 LMC member stars with good UBV photometries from the Bochum photometry data base have been first corrected individually for galactic foreground ...

An HST Study of the Substellar Population of NGC 2024
The Astrophysical Journal, 2023 We performed an HST/WFC3-IR imaging survey of the young stellar cluster NGC 2024 in three filters probing the 1.4 μ m H _2 O absorption feature, characteristic of the population of low-mass and substellar-mass objects down to a few Jupiter masses.

Measuring the Slope of the Dust Extinction Law and the Power Spectrum of Dust Clouds Using Differentially Reddened Globular Clusters [PDF]
The Astronomical Journal, 2004 We present 3 methods for measuring the Galactic dust extinction law slope R_V and a method for quantifying fine structure in dust clouds in the direction of differentially-reddened globular clusters. We apply these methods to the low- latitude globular cluster NGC4833 which displays variable extinction/reddening about a mean ~ 1.

The Astrophysical Journal LettersThe interstellar extinction law is important for interpreting observations and inferring the properties of interstellar dust grains. Based on the 993 prism/CLEAR spectra from the James Webb Space Telescope (JWST), we investigate the 0.6–5.3 μ m ...

Red and infrared colours of B stars and the reddening law in the Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 The red and infrared intrinsic colours of B stars are derived from photometric observations through the UBV(R1)cJHK and H,8 filters of 257 early-type stars. Those stars for which the UBV and H,8 measurements match the published spectral class, and which show no other signs of peculiarity, are used to determine the intrinsic photometric colours of B ...

Materialwissenschaft und Werkstofftechnik, EarlyView.An approach to quantify the mesh quality for simulations of bolted joints with formed female threads has been conducted for different meshing strategies. Depending on mesh orientation, Arbitrary‐Lagrangian‐Eulerian remeshing and mass scaling the quotient qH was evaluated.

The Modern Law Review, EarlyView.This case note critically examines the January 2026 High Court judgment in The King (on the application of The Howard League for Penal Reform) v The Secretary of State for Justice which dismissed a judicial review challenging the expansion of the use of PAVA spray in Young Offender Institutions (YOIs) in England.

Three-dimensional Reddening Maps of the Magellanic Clouds Constructed by RR Lyrae Stars
The Astronomical JournalWe present the first three-dimensional reddening maps of the Large and Small Magellanic Clouds (LMC and SMC) constructed using fundamental-mode RR Lyrae stars (RRab) from the Optical Gravitational Lensing Experiment (OGLE) survey.
