The Astrophysical JournalIn the most precise distance ladder determination of H _0 , the observed near-infrared fluxes of Cepheids are corrected for dust, assuming that the extinction law in large, star-forming spiral hosts of Type Ia supernovae (SNe Ia) is similar to the Milky ...

The deep eclipses of RW Aur revisited by long‐term photometric and spectroscopic monitoring
Astronomische Nachrichten, Volume 345, Issue 4, May 2024.Abstract RW Aurigae is a young stellar system containing a classical T Tauri star as the primary component. It shows deep, irregular dimmings, first detected in 2010. At the University Observatory Jena, we carried out optical follow‐up observations. We performed multiband (BVRI) photometry of the system with the Cassegrain‐Teleskop‐Kamera II and the ...

The Gaia-ESO Survey: addressing extinction and reddening towards NGC6530 [PDF]
, 2016 Accurate knowledge of the amount of interstellar extinction and its properties is crucial to determine fundamental stellar parameters, such as luminosities, masses and ages.

Interstellar reddening using the VO and determination of PNe distances
, 2009 We discuss the application of Virtual Observatory (VO) tools for the determination of interstellar reddening by the use of photometric data and spectral type information of stars near a selected line of sight. We illustrate this technique with an example

Differential Reddening and Extinction Law Analyses of Galactic Open Clusters
The Astronomical JournalExtinction significantly affects open cluster (OC) parameters and their use in studies of Galactic structure, yet homogeneous large-sample measurements of OC extinction properties remain limited.

On the Methods of Correction for the Interstellar Reddening of Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1968 Knowledge of the interstellar extinction is of great importance for the study of the properties of planetary nebulae. An estimate of the interstellar reddening for an individual nebula may be obtained by means of three independent methods. In the first method the observed Balmer decrement is compared with the theoretical decrement (case B of Baker and ...

Searching for a variability of interstellar reddening in the line of sight of NGC 4833
, 2015 International audienceThe globular cluster NGC 4833 lies near the galactic plane. It is known to exhibit a strong differential reddening caused by several galactic interstellar clouds in its line of sight.

Reddening maps of the Magellanic Clouds using spectral energy distribution fitting of red giants
Astronomy & AstrophysicsContext. Robust reddening maps of the Large and Small Magellanic Clouds (LMC and SMC) are crucial for a wide range of astrophysical studies, including the calibration of the cosmic distance ladder, investigations of stellar populations in low-metallicity

The Panchromatic Hubble Andromeda Treasury. XX. The Disk of M31 is Thick
The Astronomical Journal, 2023 We present a new approach to measuring the thickness of a partially face-on stellar disk, using dust geometry. In a moderately-inclined disk galaxy, the fraction of reddened stars is expected to be 50% everywhere, assuming that dust lies in a thin ...
