Quarks and Quakes
A quake model of bare strange stars for normal pulsar glitches is summarized. Three mechanisms being responsible for developing elastic stress energy are presented. It is suggested that other kinds of glitches (e.g, the frequency glitch in KS 1947+300 and in AXP/SGRs) could represent the bulk-strain-induced quakes. The apparent field increase of normal pulsars into “magnetars” could be the resu...
متن کاملQuakes in Solid Quark Stars
A starquake mechanism for pulsar glitches is developed in the solid quark star model. It is found that the general glitch natures (i.e., the glitch amplitudes and the time intervals) could be reproduced if solid quark matter, with high baryon density but low temperature, has properties of shear modulus μ = 1030∼34 erg/cm3 and critical stress σc = 1018∼24 erg/cm3. The post-glitch behavior may re...

History demonstrates the great value of frequency domain data for understanding the physics of complex processes. The Cumulative Spectral Power (CSP) opens a new window into the study of earthquake evolution [2]. For this purpose, the CSP has a significant advantage over the Power Spectral Density (PSD) from which it is derived by integration. The FFT spectrum used to generate the PSD is inhere...
متن کاملScience and law: rattled by quakes.
WHEN GOOD RISK ASSESSMENTS IMPROVE FINANCIAL, ENVIRONMENTAL, OR HEALTH DECISIONS, society often does not recognize the combined efforts of stakeholders who brought good management to bear. But when disaster strikes, the interface between science and public policy can come into question. A recent example is the 6.3-magnitude earthquake that struck the Italian city of L’Aquila in early April 2009...
متن کامل“Price-Quakes” Shaking the World's Stock Exchanges
BACKGROUND Systemic risk has received much more awareness after the excessive risk taking by major financial instituations pushed the world's financial system into what many considered a state of near systemic failure in 2008. The IMF for example in its yearly 2009 Global Financial Stability Report acknowledged the lack of proper tools and research on the topic. Understanding how disruptions ca...
