Stars are transparent to the passage of primordial black holes (PBHs) and serve as seismic detectors for such objects. The gravitational field of a PBH squeezes a star and causes it to ring acoustically. We calculate the seismic signature of a PBH passing through the Sun. The background for this signal is the observed spectrum of solar oscillations excited by supersonic turbulence. We predict that PBHs more massive than 10(21)  g (comparable in mass to an asteroid) are detectable by existing…

Detectable Seismic Consequences of the Interaction of a Primordial Black Hole with Earth
Galaxies observed today are likely to have evolved from density perturbations in the early universe. Perturbations that exceeded some critical threshold are conjectured to have undergone
Stellar Shocks from Dark Matter Asteroid Impacts.
Macroscopic dark matter is almost unconstrained over a wide "asteroidlike" mass range, where it could scatter on baryonic matter with geometric cross section. We show that when such an object travels
Primordial Black Holes: sirens of the early Universe
Primordial Black Holes (PBHs) are, typically light, black holes which can form in the early Universe. There are a number of formation mechanisms, including the collapse of large density
Constraining primordial black-hole bombs through spectral distortions of the cosmic microwave background
We consider the imprint of superradiant instabilities of nonevaporating primordial black holes (PBHs) on the spectrum of the cosmic microwave background (CMB). In the radiation dominated era, PBHs
Improved Theoretical Predictions of Microlensing Rates for the Detection of Primordial Black Hole Dark Matter
Primordial black holes (PBHs) remain a dark matter (DM) candidate of the Standard Model of Particle Physics. Previously, we proposed a new method of constraining the remaining PBH DM mass range using
Semiclassical geons as solitonic black hole remnants
We find that the end state of black hole evaporation could be represented by non-singular and without event horizon stable solitonic remnants with masses of the order the Planck scale and up to ~ 16

Abstract Linkages between astronomy and physics have always been intimately close and mutually stimulating. Most often it was physics that served astronomy with its explanatory power. Today, however,
Graviatoms with de Sitter Interior
We present a graviatom with de Sitter interior as a new candidate to atomic dark matter generically related to a vacuum dark energy through its de Sitter vacuum interior. It is a gravitationally

CoRoT Measures Solar-Like Oscillations and Granulation in Stars Hotter Than the Sun
TLDR
The CoRoT (Convection Rotation and Planetary Transits) satellite, launched in December 2006, has now measured oscillations and the stellar granulation signature in three main sequence stars that are noticeably hotter than the sun.
Gamma rays from primordial black holes
This paper examines the possibilities of detecting hard ..gamma..-rays produced by the quantum-mechanical decay of small black holes created by inhomogeneities in the early universe. Observations of
NO OBSERVATIONAL CONSTRAINTS FROM HYPOTHETICAL COLLISIONS OF HYPOTHETICAL DARK HALO PRIMORDIAL BLACK HOLES WITH GALACTIC OBJECTS
It was suggested by several authors that hypothetical primordial black holes (PBHs) may contribute to the dark matter (DM) in our Galaxy. There are strong constraints based on the Hawking evaporation
The Asteroseismic potential of Kepler : first results for solar-type stars
We present preliminary asteroseismic results from Kepler on three G-type stars. The observations, made at one-minute cadence during the first 33.5 days of science operations, reveal high
Primordial Black Hole Formation during the QCD Epoch
We consider the formation of horizon-size primordial black holes (PBH{close_quote}s) from pre-existing density fluctuations during cosmic phase transitions. It is pointed out that the formation of
Black hole explosions?
QUANTUM gravitational effects are usually ignored in calculations of the formation and evolution of black holes. The justification for this is that the radius of curvature of space-time outside the

We update the constraints on the fraction of the Universe going into primordial black holes in the mass range 10{sup 9}-10{sup 17} g associated with the effects of their evaporations on big bang
EROS and MACHO combined limits on planetary-mass dark matter in the galactic halo
The EROS and MACHO collaborations have each published upper limits on the amount of planetary-mass dark matter in the Galactic halo obtained from gravitational microlensing searches. In this Letter,
The Primordial black hole mass spectrum
We examine what mass spectrum of primordial black holes should result if the early universe consisted of small density fluctuations superposed on a Friedmann background. It is shown that only a
Limits on the Macho Content of the Galactic Halo from the EROS-2 Survey of the Magellanic Clouds
The EROS-2 project was designed to test the hypothesis that massive compact halo objects (the so-called ''machos'') could be a major component of the dark matter halo of the Milky Way galaxy. To this
