Asian Precipitation Changes in the Past Millennium: Projection of Volcanic Forcing Onto Internal Mode

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Asian precipitation changes over multiple time scales have been extensively studied, yet the relative roles of external forcing and internal variability in shaping the large‐scale Asian precipitation pattern over the past millennium remain underexplored. Here, we demonstrate that the tripolar pattern of decadal precipitation variability across

Evolution of Cataclysmic Variables with Binary-driven Mass Loss during Nova Eruptions

The Astrophysical Journal
The discrepancies between observations and theoretical predictions of cataclysmic variables (CVs) suggest that there exists unknown angular-momentum-loss mechanism(s) besides magnetic braking and gravitational radiation.

The Photometric Period and Variability of the Cataclysmic Variable V849 Herculis (PG 1633+115)

, 2012
We report time-resolved photometry of the cataclysmic variable V849 Her, and measure a period of 0.1414 \pm 0.0030 days (3.394 \pm 0.072 hours). We also present photometry taken over several weeks in 2010 and 2011, as well as light curves from 1995 to ...

Characterization and Localization of Chemical Explosions and Lightning Flashes by a Flotilla of Stratospheric Balloons

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract On 3 August 2021, a flotilla of four Heliotrope solar hot air balloons was launched from central New Mexico (USA). The balloons, equipped with microbarometers, flew from sunrise to sunset at altitudes between 17 and 22 km. During the flight, eight chemical explosions ranging from 45 to 136 kg TNT equivalent and a thunderstorm occurred in the ...

Irradiation of the secondary star in cataclysmic variables [PDF]

Monthly Notices of the Royal Astronomical Society, 1992
It is shown how the relative strength of the Na I doublet over the surface of the secondary star can be calculated from radial velocity curves obtained using the Na I absorption feature around 8190 A. The results for 11 dwarf novae and one magnetic cataclysmic binary system are presented.

Gas flow in cataclysmic variable stars

The Astrophysical Journal, 1975
A numerical hydrodynamic scheme, applicable to gas flow in binary stars, is presented which incorporates the effects of pressure and gravitational forces, radiative cooling, and shock formation. The method is used to study gas flow originating from Roche lobe overflow through the inner Lagrangian point, L$sub 1$, in a binary star modeled to resemble ...

Eastern United States: Potential Range for Ecologically Based Coastal Defenses in 2100

Global Change Biology Communications, Volume 1, Issue 1, March 2026.
These maps show where black mangroves can potentially thrive along the US east coast by the end of the 21st century under several climate scenarios. Similar work was done for oyster reefs and saltmarshes. ABSTRACT Eco‐defenses (mangroves, oyster reefs, and saltmarshes) are ecosystems that can help to mitigate the effects of natural hazards and erosion ...

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.
