Variable G versus the Accelerated Expansion of the Universe
Open Astronomy, 2017 It is shown that the hypothesis of permitting variability of the Newtonian constant G, increasing with the local density of dark matter, implies that there is no need for the introduction of a cosmological constant or accelerated expansion of the ...

Star Formation as Seen by Low Mass Stars
Acta Polytechnica CTU Proceedings, 2014 Using the Hubble Space Telescope (HST) we have characterised and compared the physical properties of a large sample of pre-main sequence (PMS) stars spanning a wide range of masses (0:5 - 4Mʘ), metallicities (0:1 - 1 Zʘ) and ages (0:5 - 30 Myr).

Observational data on galactic supernova remnants: I. The supernova remnants within l = 0◦ - 90◦ [PDF]
Serbian Astronomical Journal, 2003 We have collected all the available data on Galactic supernova remnants given in the literature. The data on Galactic supernova remnants located in the Galactic longitude interval l=0◦-90◦ in all the spectral bands are presented in this work.

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...

The Plant Genome, Volume 19, Issue 1, March 2026.Abstract Oxalis oulophora, a diploid species closely related to the octoploid Andean tuber crop oca (Oxalis tuberosa), was selected for whole‐genome sequencing to aid in understanding the origins of polyploidy and domestication in oca and its relatives (crop wild relatives).

Supernova 1988A: another clumped supernova [PDF]
Monthly Notices of the Royal Astronomical Society, 1991 The evolution of the forbidden multiplet (1F) oxygen lines in the optical spectrum of SN 1988A is used to determine the evolution of the optical depth in those transitions which in turn can be used to derive the number density of oxygen in the ejecta.

Energy Partition at a Collisionless Supercritical Quasi‐Parallel Shock
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Shocks in collisionless astrophysical plasmas redistribute some of the incident flow energy into both thermal and non‐thermal energy. Quantifying the partition of that energy amongst various particle species or their sub‐populations, and electromagnetic energy, represents a fundamental goal of shock physics.

Hydrogen-rich to stripped-envelope: observational continuity and biases in CCSNe
Frontiers in Astronomy and Space SciencesAlthough historically classified into discrete subclasses, there is growing evidence that indicates that core-collapse supernovae (CCSNe) categories often overlap, reflecting continuous variations in progenitor structure, mass-loss history, and ...
