Retired A Stars and Their Companions: Exoplanets Orbiting Three Intermediate-Mass Subgiants [PDF]
, 2007 We report precision Doppler measurements of three intermediate-mass subgiants from Lick and Keck Observatories. All three stars show variability in their radial velocities consistent with planet-mass companions in Keplerian orbits.

Minor planet astrophotometry [PDF]
, 2012 Historically, the Minor Planet Center (MPC) has concentrated on improving the quality of the astrometric observations and the resulting orbits of minor planets. In light of long-standing complaints in the literature about the quality of the photometric parameters for the minor planets, there has been a need to improve the quality of the absolute ...

Advanced Materials, EarlyView.Mechano‐activated partially disordered spinel LiMn2O4 is demonstrated with high Mn utilization and a specific energy over 800 Wh kg−1 at the cathode active material (CAM) level. Surface degradation, caused by the Jahn‐Teller effect in baseline commercial carbonate electrolyte (Gen 2), intensifies Mn2+ dissolution and crosstalk at high potentials ...

Advanced Materials, EarlyView.Solid‐state batteries promise high energy density and safety for electric vehicles. This study examines the densification of slurry‐casted Li₆PS₅Cl separator tapes, highlighting the role of particle size distribution and uni‐axial pressure. Wet milling refines particles while preserving conductivity, and a critical compaction threshold leads to ...

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes
Advanced Materials, EarlyView.Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Integrated software package STAMP for minor planets [PDF]
The integrated software package STAMP allowed for rapid and exact reproduction of the tables of the year-book 'Ephemerides of Minor Planets.' Additionally, STAMP solved the typical problems connected with the use of the year-book. STAMP is described. The

On the Period Distribution of Close-In Extrasolar Giant Planets [PDF]
, 2004 Transit (TR) surveys for extrasolar planets have recently uncovered a population of ``very hot Jupiters,'' planets with orbital periods of P< 3 d. At first sight this may seem surprising, given that radial velocity (RV) surveys have found a dearth of ...

Bimodal Spin Switch Emerging from Hybridized 2D MoS2/Ferromagnet Interfaces
Advanced Materials, EarlyView.This study demonstrates a novel integration of 2D semiconductors with ferromagnets using pulsed laser deposition, revealing hybridization‐driven spin manipulation. Vertical spin valves with MoS2 and Ni(111) show exotic bimodal spin signals and strong deviations from Jullière's model. These results highlight the « 2D spinterfaces » key role in unlocking

Study of ephemeris accuracy of the minor planets [PDF]
The current state of minor planet ephemerides was assessed, and the means for providing and updating these emphemerides for use by both the mission planner and the astronomer were developed.
