Publications of the Astronomical Society of the Pacific, 1995 1994 was the year in which we saw the first images from the repaired Hubble Space Telescope; the probable detection of a diffuse intergalactic medium, a black hole in M87, and an enormous primordial deuterium abundance; the discovery of the first (and second) superluminal objects within our own galaxy; not to mention the demise of the Jovian dinosaurs.

New Arabic Records From Cairo on Supernovae 1181 and 1006
Astronomische Nachrichten, EarlyView.ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

The thermal/ sensory gravity “S.O.S.” the last phase (40°–50° C) of global warming [PDF]
INCAS BulletinThe gravitational buckling is an ice hole or black hole in the frozen quantum binary space penetrated by the light ignition, the backscattering of radiant thermal energy, where the quantum light barrier (cs = 1010 m/s) breaks together with the thermal ...

Origin of an orbiting star around the galactic supermassive black hole
Proceedings of the Japan Academy. Series B, Physical and Biological Sciences, 2023 The tremendous tidal force that is linked to the supermassive black hole (SMBH) at the center of our galaxy is expected to strongly subdue star formation in its vicinity.

Astronomische Nachrichten, EarlyView.ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

Uncertainties in Historic Visual Double Star Measures—III Accurate Calibration Pairs
Astronomische Nachrichten, EarlyView.ABSTRACT Based on space‐based positions and proper motions, we present accurate rectilinear elements for 857 double star pairs over the celestial sphere. These elements allow for the computation of precision ephemeris Position Angles and Separations of these pairs.

Metals, 2015 Planets and stars are often capable of generating their own magnetic fields. This occurs through dynamo processes occurring via turbulent convective stirring of their respective molten metal-rich cores and plasma-based convection zones.

British Educational Research Journal, EarlyView.Abstract This paper uses empirical data from a longitudinal qualitative study conducted with aspirant teachers in England to propose (re)definitions of the concepts of ‘status’ and ‘safety’ as a framework with which to understand and improve teacher recruitment.

Fundamental Physics and Relativistic Laboratory Astrophysics with Extreme Power Lasers
, 2012 The prospects of using extreme relativistic laser-matter interactions for laboratory astrophysics are discussed. Laser-driven process simulation of matter dynamics at ultra-high energy density is proposed for the studies of astrophysical compact objects ...
