Microlensing maps for the galactic bulge [PDF]
The Astrophysical Journal, 1994 Microlensing maps -- that is, contours of equal numbers of events per $10^6$ source stars -- are provided for the inner Galaxy under two alternative hypotheses : (1) the bulge is an oblate axisymmetric spheroid or (2) the bulge is a prolate bar. Oblate spheroids yield a total of $\sim 12$ events per year per $10^6$ stars at Baade's Window ($\sim 15 ...

The Impact of Data Resolution on Planetary Compressional Structure Analysis
Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Planetary studies of compressional structures are fundamental for understanding the tectonics and thermal evolution of planetary bodies. Compressional features are commonly characterized by their morphology, which in turn is strongly dependent on the spatial resolution of topographic data.

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Lava tubes are subsurface volcanic conduits formed during effusive basaltic eruptions and are considered key targets for planetary exploration. Orbital remote sensing on the Moon and Mars has identified numerous collapse pits interpreted as possible surface expressions of underlying lava tube systems. However, the limited resolution of current

The UV spectrum of the Galactic bulge [PDF]
, 2007 The elliptical galaxies show in their spectra at ultraviolet wavelengths an unexpected flux . SdB (alias called Extreme Horizontal Branch) stars are believed to be responsible of this feature.

New Light on Dark Extended Lenses with the Roman Space Telescope
The Astrophysical Journal LettersThe Roman Space Telescope’s Galactic Bulge Time Domain Survey will constitute the most sensitive microlensing survey of the Galactic bulge to date, opening up new opportunities to search for dark matter (DM). Many extensions of the Standard Model predict

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1763-1787, August 2026.Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...

Pre‐Existing Plasmaspheric Density Structure
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract We perform a basic model experiment: we run two nearly identical plasmapause simulations, differing only by their initial conditions. The first run contains initial fine‐scale and mesoscale structure, and the second run is initialized with a featureless, circular plasmapause.

Modeling Asteroseismic Yields for the Roman Galactic Bulge Time-domain Survey
The Astrophysical JournalThe Galactic Bulge Time-Domain Survey (GBTDS) of the Roman Space Telescope will take high-cadence data of the Galactic bulge. We investigate the asteroseismic potential of this survey for red giants.
