KIC 4552982: outbursts and pulsations in the longest-ever pseudo-continuous light curve of a ZZ Ceti

EPJ Web of Conferences, 2015
KIC 4552982 was the first ZZ Ceti (hydrogen-atmosphere pulsating white dwarf) identified to lie in the Kepler field, resulting in the longest pseudo-continuous light curve ever obtained for this type of variable star.

A Dynamical Model for IRAS 00500+6713: The Remnant of a Type Iax Supernova SN 1181 Hosting a Double Degenerate Merger Product WD J005311

The Astrophysical Journal
IRAS 00500+6713 is a hypothesized remnant of a Type Iax supernova SN 1181. Multiwavelength observations have revealed its complicated morphology; a dusty infrared ring is sandwiched by the inner and outer X-ray nebulae. We analyze the archival X-ray data

Corporate Social Responsibility or Strategic Opportunism? Evidence From High and New Technology Firms

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Corporate Social Responsibility (CSR) presents a dual nature in practice. Beyond its explicit ethical imperatives, it can be strategically instrumentalized to manage external pressures, shape public impression, and even divert attention from corporate misconduct. Acknowledging this complexity, this study investigates the conditions under which

Tidal Disruption of Planetesimals from an Eccentric Debris Disk Following a White Dwarf Natal Kick

The Astrophysical Journal Letters
The surfaces of many white dwarfs are polluted by metals, implying a recent accretion event. The tidal disruption of planetesimals is a viable source of white dwarf pollution and offers a unique window into the composition of exoplanet systems.

Optical identification of the companion to PSR J1911-5958A, the pulsar binary in the outskirts of NGC 6752

, 2003
We report on the identification of the optical counterpart of the binary millisecond pulsar PSR J1911-5958A, located in the outskirts of the globular cluster NGC 6752. At the position of the pulsar we find an object with V=22.08, B-V=0.38, U-B=-0.49. The
