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 Optical Extinction Law Depends on Magnetic Field Orientation: The RV–ψ Relation
The Astrophysical JournalFor aspherical interstellar dust grains aligned with their short axes preferentially parallel to the local magnetic field, the amount of extinction per grain is larger when the magnetic field is along the line of sight and smaller when in the plane of ...

Interstellar extinction towards the inner Galactic Bulge [PDF]
, 1999 DENIS observations in the J (1.2 micron) and K_S (2.15 micron) bands together with isochrones calculated for the RGB and AGB phase are used to draw an extinction map of the inner Galactic Bulge.

Limitations of the modified blackbody fit method for determining molecular cloud properties
Astronomische Nachrichten, Volume 345, Issue 4, May 2024.Abstract Achieving a comprehensive understanding of the star and planet formation process is one of the fundamental tasks of astrophysics, requiring detailed knowledge of the physical conditions during the different phases of this process. During the earliest stages, that is, concerning physical processes in molecular clouds and filaments, the column ...

Chiroptical properties of membrane glycerophospholipids and their chiral backbones
Chirality, Volume 36, Issue 3, March 2024.Examination of the interaction of glycerophospholipids with circularly polarized light suggests that direct induction of symmetry breaking to membrane lipids by chiral photons is unlikely. However, anisotropy spectra of certain analogs indicate potential alternative mechanisms for the origins of membrane lipid homochirality, providing insights into the

An Empirical Extinction Curve Revealed by Gaia XP Spectra and LAMOST
The Astrophysical JournalWe present a direct measurement of extinction curves using corrected Gaia XP spectra of the common sources in Gaia DR3 and LAMOST DR7. Our analysis of approximately 370,000 high-quality samples yielded a high-precision average extinction curve for the ...

Facing Apocalypse: Climate Mobilities and the Cinematic Child
Sociology Lens, Volume 37, Issue 1, Page 105-115, March 2024.Abstract This article engages with the representations and meanings of child figures within US films about environmentally induced displacement. At the intersection between film studies, childhood studies, and the emerging scholarship on climate mobilities (Boas et al., 2022), it explores the ways in which three contemporary apocalyptic films—The Road (

IR emission and UV extinction in two open clusters [PDF]
Recent models of interstellar extinction have shown the importance of understanding both the UV and IR properties of interstellar dust grains. IRAS data have shown variations in 60 and 100 micron emissions presumably due to the presence of IR cirrus ...

LAMOST Spectroscopy and Gaia Photo-Astrometry for an Interstellar Extinction Study
GalaxiesThe aim of this work is to establish the present accuracy and convergence of available estimates of galactic extinction. We determine the galactic interstellar extinction in selected high-latitude areas of the sky based on Gaia DR3 astrometry and ...
