DEATH OF A STAR. “Once the nuclear fuel is entirely burnt out, there remains no sufficient pressure to resist the attractive force of gravity, consequently, the star experiences the stellar death, a phenomenon known as gravitational collapse.” https://lnkd.in/dnMiFPu View in LinkedIn

THE REAL ROOTS. “Space is a violent place, strewn with galaxies that have cannibalized each other to survive. Some of these survivors are galactic fossils, revealing glimpses of the past because they formed in the early universe.” https://lnkd.in/dVQCih6 View in LinkedIn

PSYCHOANALYSIS “has further taught us that our intellect is a feeble and dependent thing, a plaything and tool of our instincts and affects, and that we are all compelled to behave cleverly or stupidly according to the commands of our [emotional] attitudes and internal resistances.” (Freud). https://lnkd.in/dawKbt4 View in LinkedIn

THEORY CRITICAL. “In general, one cannot observe the dense matter directly, but the observations of stellar properties like mass, radius and cooling behaviour have to be interpreted using theoretical models in order to constrain the equation of state of stellar matter. In order to calculate strong interaction matter relevant for compact stars as well as heavy-ion physics we have developed and studied hadronic and hadron-quark models within the so-called chiral mean field (CMF) approach.” https://lnkd.in/dGXZSrf View in LinkedIn

PHYSICS = ASTRONOMY. “Studying the phase structure of hot and dense strongly interacting matter is central to many experimental and theoretical efforts in modern nuclear physics. As a complement to a range of ultrarelativistic heavy-ion collision experiments targeting in particular hot matter, the environment of neutron stars samples high-density matter at very low temperature.” https://lnkd.in/dGXZSrf View in LinkedIn

PASTA MATTER. “In the first part of this paper, we investigate the possible existence of a structured hadron-quark mixed phase in the cores of neutron stars. This phase, referred to as the hadron-quark pasta phase, consists of spherical blob, rod, and slab rare phase geometries.” https://lnkd.in/dSt3xgn View in LinkedIn

STRANGE QUARK STARS. “A thorough search in the currently detected ~2950 exoplanets around normal main-sequence stars has failed to identify any stable close-in objects that meet the SQM criteria, i.e., lying in the tidal disruption region for normal matter planets. However, the pulsar planet PSR J1719-1438B, with an orbital radius of ~6 × 10(10) cm and orbital period of 7837 s, is, encouragingly, found to be a good candidate.” (SQM = strange quark matter). https://lnkd.in/d-4qzTw View in LinkedIn

LOWEST ENERGY STATE. “The true ground state of hadronic matter may be strange quark matter (SQM). Consequently, observed pulsars may actually be strange quark stars, but not neutron stars. However, proving or disproving the SQM hypothesis still remains a difficult problem to solve due to the similarity between the macroscopical characteristics of strange quark stars and neutron stars.” https://lnkd.in/d-4qzTw View in LinkedIn

STRANGE DWARFS. “We investigate the stability of "strange dwarfs": white-dwarf-sized stars with a density discontinuity between a small dense core of quark matter and a thick low-density mantle of degenerate electrons. Previous work on strange dwarfs suggested that such a discontinuity could stabilize stars that would have been classified as unstable by the conventional criteria based on extrema in the mass–radius relation. We investigate the stability of such stars by numerically solving the Sturm–Liouville equations for the lowest-energy modes of the star. We find that the conventional criteria are correct, and strange dwarfs are not stable.” https://lnkd.in/dJXt729 View in LinkedIn
