Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

SUPERNOVAE EXPLOSIONS THEORY AND COMPACT REMNANT OF SN 1987A

Odessa Astronomical Publications, 2012
Hydrodynamics of massive star explosion within a non-spherical supernova model is presented. The explosive burning is computed in the He-core of a progenitor.

Modeling the interaction of thermonuclear supernova remnants with circumstellar structures: The case of Tycho's supernova remnant

, 2013
The well-established Type Ia remnant of Tycho's supernova (SN 1572) reveals discrepant ambient medium density estimates based on either the measured dynamics or on the X-ray emission properties. This discrepancy can potentially be solved by assuming that

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Engineering a Stable Solid–Electrolyte Interphase through a Novel Trifluoromethyl‐Free Lithium Salt for Lithium Metal Polymer Batteries

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 ...

Inhomogeneous Stellar Mixing in the Final Hours before the Cassiopeia A Supernova

The Astrophysical Journal
Understanding stars and their evolution is a key goal of astronomical research and has long been a focus of human interest. In recent years, theorists have paid much attention to the final interior processes within massive stars, as they can be essential

Unveiling the nature of RX J0002+6246 with XMM-Newton

, 2007
The X-ray source RX J0002+6246 was discovered close to the supernova remnant CTB1 in a ROSAT observation performed in 1992. The source phenomenology (soft spectrum, apparent lack of counterparts, possible pulsations at 242 ms, hints for surrounding ...
