Polar Orbits around the Newly Formed Earth–Moon Binary System
The Astrophysical JournalWe examine the dynamics and stability of circumbinary particles orbiting around the Earth–Moon binary system. The moon formed close to the Earth (semimajor axis a _EM ≈ 3 R _⊕ ) and expanded through tides to its current day semimajor axis ( a _EM = 60 R ...

Longitudinal development of a substorm brightening arc [PDF]
Annales Geophysicae, 2009 We present simultaneous THEMIS-ground observations of longitudinal (eastward) extension of a substorm initial-brightening arc at Gillam (magnetic latitude: 65.6°) at 08:13 UT on 10 January 2008.

Quantifying the Impact of Relativistic Precession on Tidal Disruption Event Light Curves
Astronomische Nachrichten, EarlyView.ABSTRACT The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impact of precession on the light curves of tidal disruption events (TDE).

Roles of 2D halide perovskites in 2D/3D heterojunctions for high‐performance perovskite solar cells
Bulletin of the Korean Chemical Society, EarlyView.This review establishes a design framework for two‐dimensional (2D)/three‐dimensional (3D) perovskite heterojunctions, redefining the 2D perovskite layer as an active semiconductor component. We classify 2D structures by spacer chemistry and analyze their roles within the heterojunction.

Effects of Latitude-Dependent Gravity Wave Source Variations on the Middle and Upper Atmosphere
Frontiers in Astronomy and Space Sciences, 2021 Atmospheric gravity waves (GWs) are generated in the lower atmosphere by various weather phenomena. They propagate upward, carry energy and momentum to higher altitudes, and appreciably influence the general circulation upon depositing them in the middle

A grid of polarization models for Rayleigh scattering planetary atmospheres
, 2009 We investigate the intensity and polarization of reflected light from planetary atmospheres. We present a large grid of Monte Carlo simulations for planets with Rayleigh scattering atmospheres. We discuss the disk-integrated polarization for phase angles

Clusters of galaxies in the microwave band: influence of the motion of the Solar System [PDF]
, 2004 In this work we consider the changes of the SZ cluster brightness, flux and number counts induced by the motion of the Solar System with respect to the frame defined by the cosmic microwave background (CMB).
