Massive luminous early type stars in the LMC - I. The reddening of individual stars and the LMC reddening law [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 ...

The photometry and kinematics studies of NGC 2509 derived from Gaia DR3 [PDF]
Scientific ReportsThis research uses the third edition of the Gaia Data Release (DR3) to re-investigate the open star cluster NGC 2509. We employed the pyUPMASK Python package and HDBSCAN algorithms to identify the cluster member stars.

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 ...

The Astronomical Journal, 1982 Positions, identification charts, UBVRIKLMN photometry and spectral types are given for stars, illuminating reflection nebulae that are visible on the POSS prints, which have been identified in five associations. With a ratio of total to selective extinction of 4.2, the reddening law applicable to the dust clouds in which the stars are embedded is ...

Reddening law and interstellar dust properties along Magellanic sight-lines
Astrophysics and Space Science, 2007 This study establishes that SMC, LMC and Milky Way extinction curves obey the same extinction law which depends on the 2200 Å bump size and one parameter, and generalizes the Cardelli, Clayton and Mathis (Cardelli et al., Astrophys. J.

Reddening Cheeks and Inducing Sweat: The Logic of Party Law in Xi Jinping’s China
Hague Journal on the Rule of LawAbstract The Chinese Communist Party under Xi Jinping has spent the past 13 years creating an “intraparty regulatory system,” or what this article calls “Party law.” Scholars ascribe different meanings to this system and its implications for Chinese law and governance.

Reddening and the Extinction Law at High Galactic Latitude
The Astrophysical Journal, 2005 We present near-infrared (JHKL) photometry of 103 southern stars located behind translucent interstellar clouds at high Galactic latitude. Our data are combined with visual photometry and spectral type information from the literature in a detailed analysis of the wavelength dependence of interstellar extinction by dust in these high-latitude clouds. We

Galactic reddening in 3D from stellar photometry – an improved map [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We present a new 3D map of interstellar dust reddening, covering three quarters of the sky (declinations of δ ≳ −30°) out to a distance of several kiloparsecs. The map is based on high-quality stellar photometry of 800 million stars from Pan-STARRS 1 and

Cepheid Metallicity in the Leavitt Law (C–MetaLL) survey
Astronomy & AstrophysicsContext. The C-MetaLL project has provided homogeneous spectroscopic abundances of 290 Classical Cepheids (DCEPs) for which we have the intensity-averaged magnitudes in multiple optical and NIR bands, periods, pulsation modes, and Gaia parallaxes ...
