Common envelope jets supernova (CEJSN) impostors resulting from a neutron star companion [PDF]
, 2018 We propose a new type of repeating transient outburst initiated by a neutron star (NS) entering the envelope of an evolved massive star, accreting envelope material and subsequently launching jets which interact with their surroundings. This interaction is the result of either a rapid expansion of the primary star due to an instability in its core near

Stellar Envelopes as Sources of Broad Line Region Emission: New Possibilities Allowed [PDF]
Astron.Astrophys. 394 (2002) 415-434, 2002 In Active Galactic Nuclei (AGNs) the presence of a star cluster around the central black hole can have several effects on the dynamics and the emission of the global system. In this paper we analyze the interaction of stellar atmospheres with a wind outflowing from the central region of the AGN nucleus.

Exotic mitotic mechanisms [PDF]
, 2012 The emergence of eukaryotes around two billion years ago provided new challenges for the chromosome segregation machineries: the physical separation of multiple large and linear chromosomes from the microtubule-organizing centres by the nuclear envelope.

The nuclear envelope as a chromatin organizer [PDF]
Nucleus, 2011 In the past 15 years our perception of nuclear envelope function has evolved perhaps nearly as much as the nuclear envelope itself evolved in the last 3 billion years. Historically viewed as little more than a diffusion barrier between the cytoplasm and the nucleoplasm, the nuclear envelope is now known to have roles in the cell cycle, cytoskeletal ...

Lem2p (LEM2) and Cmp7p (CHMP7) function in ESCRT-dependent nuclear envelope remodeling in fission yeast [PDF]
, 2016 ESCRT‐III proteins have been implicated in sealing the nuclear envelope in mammals, both during nuclear assembly and following mechanical disruption. This sealing process requires the ESCRT‐II/ESCRT‐ III hybrid protein CHMP7 and the AAA ATPase VPS4.

Evolution: functional evolution of nuclear structure. [PDF]
, 2011 The evolution of the nucleus, the defining feature of eukaryotic cells, was long shrouded in speculation and mystery. There is now strong evidence that nuclear pore complexes (NPCs) and nuclear membranes coevolved with the endomembrane system, and that ...

Nuclear Rotation Curves of Galaxies in the CO Line Emission [PDF]
, 1997 We have obtained high-resolution position-velocity (PV) diagrams along the major axes of the central regions of nearby galaxies in the CO-line emission using the Nobeyama 45-m telescope and the Millimeter Array.

Ion channels in the nuclear envelope [PDF]
Nature, 1990 Cell nuclei are capable of partitioning a wide variety of molecules from the cytosol, including macromolecules such as proteins and RNA, and smaller peptides, amino acids, sugars and Na+ and K+ ions, all of which can be accumulated in or excluded from the nuclear domain.

On algebras of holomorphic functions of a given type [PDF]
, 2011 We show that several spaces of holomorphic functions on a Riemann domain over a Banach space, including the nuclear and Hilbert-Schmidt bounded type, are locally $m$-convex Fr\'echet algebras.

Muon-Induced Nuclear Magnetic Moments in Spinless Muonic Atoms: A Simple Estimate [PDF]
arXiv, 2023 The magnetic field generated by a bound muon in heavy muonic atoms results in an induced nuclear magnetic dipole moment even for otherwise spinless nuclei. This dipole moment interacts with the muon, altering the binding energy of the muonic state. We investigate the relation of this simple, semi-classical-insriped approach to nuclear polarisation (NP)
