Captured at millimeter wavelengths: a flare from the classical T Tauri star DQ Tauri [PDF]
Astronomy & Astrophysics, 2008 For several hours on 2008 April 19 the T Tauri spectroscopic binary DQ Tau was observed to brighten, reaching a maximum detected flux of 468 mJy and likely making it (briefly) the brightest object at 3 mm in the Taurus star-forming region. We present the light curve of a rarely before observed millimeter flare originating in the region around a pre ...

Gravitoastronomy with neutron stars [PDF]
, 2004 Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.

Probing the composition of sub-millisecond rotating compact stars by r-modes instability [PDF]
, 2012 We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

Gravitational Redshift Detection from the Magnetic White Dwarf Harbored in RX J1712.6–2414
The Astrophysical Journal, 2023 Gravitational redshift is a fundamental parameter that allows us to determine the mass-to-radius ratio of compact stellar objects, such as black holes, neutron stars, and white dwarfs (WDs).

Theoretical results of one class of multiderivative methods through order stars [PDF]
, 2011 Order stars are applied to Brown (K,L) methods. They are displayed pictorially for a selection of methods and are used to provide succinct proofs of existing results.

Polarization observations of DQ Her stars and other cataclysmic variables [PDF]
Monthly Notices of the Royal Astronomical Society, 1986 © Royal Astronomical Society. Linear and circular polarizations are presented for the DQ Her stars FO Aqr, AE Aqr, EX Hya, AO Psc and V1223 Sgr and for 17 other cataclysmic variables. Upper limits (~0.1 per cent in circular) are set to any periodic varia- tions in the polarization for the DQ Her stars.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

A New Window for Studying Intermediate Polars and Tilted Accretion Disk Precession
The Astrophysical JournalTV Col is a long-period eclipsing intermediate polar (IP) prototype star for the negative superhump (NSH) system. We investigate the eclipse minima, eclipse depth, and NSH amplitude based on TESS photometry.
