Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

Spectroscopic Follow-up on Potential Magnetic Cataclysmic Variables

The Astronomical Journal
Spectroscopic observations of nine cataclysmic variables that have been postulated to contain magnetic white dwarfs were obtained to further characterize their classifications, orbital parameters, inclinations, and/or accretion properties.

Fermi-LAT detections of the classical novae V1723 Sco and V6598 Sgr in a multi-wavelength context

Astronomy & Astrophysics
Context. Numerous classical novae have been observed to emit γ-rays (E > 100 MeV) detected by the Fermi-LAT. The prevailing hypothesis attributes this emission to the interaction of accelerated particles within shocks in the nova ejecta.

Winds from Cataclysmic Variables [PDF]

International Astronomical Union Colloquium, 1997
AbstractThe winds associated with high states of non-magnetic (diskaccreting) cataclysmic variables are described and discussed. A quick summary of the basic phenomenology is given, and followed by a presentation of some of the more important recent developments in our understanding.

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War

Anthropology of Consciousness, Volume 37, Issue 1, Spring 2026.
ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

Infrared Properties of Cataclysmic Variables from 2MASS: Results from the 2nd Incremental Data Release

, 2001
Because accretion-generated luminosity dominates the radiated energy of most cataclysmic variables, they have been ``traditionally'' observed primarily at short wavelengths.

New Observations of the Old Magnetic Nova GQ Muscae

Open Astronomy, 2014
Photometric observations of GQ Mus performed between 1992 and 2011 are reported. We find that the total amplitude of the orbital modulation of its brightness decreased from ~ 0.9 mag in 1992 to ~ 0.2 mag in 2010, becoming comparable to the amplitude of ...

Discovering Cataclysmic Variables from the Rubin Observatory LSST

The Astrophysical Journal Supplement Series
The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) will provide a windfall of new transients and variable sources. Here we have performed mock observation simulations to understand LSST’s expected detection rates for cataclysmic ...

Early Photometric and Spectral Evolution of Nova Cygni 2014 (V2659 Cyg)

Open Astronomy, 2015
We present optical spectroscopic and UBV (RI)C photometric observations of Nova Cygni 2014 (V2659 Cyg) from its rebrightening to the nebular stage. After the first maximum, the nova underwent several irregular flare-like rebrightenings, with amplitudes ...

Temporary Equilibrium Mass Transfer Rate in Cataclysmic Variables?

The Astrophysical Journal
The separation of a binary system increases or decreases over time, governed by angular momentum (AM) changes. In cataclysmic variables (CVs), Roche-lobe overflow from the red dwarf (RD) to the white dwarf (WD) redistributes AM within the system through ...
