The stellar mass ratio of GK Persei [PDF]
, 2001 We study the absorption lines present in the spectra of the long-period cataclysmic variable GK Per during its quiescent state, which are associated with the secondary star.

A Surrogate Model for Gravitational Wave Signals from Comparable- to Large- Mass-Ratio Black Hole Binaries [PDF]
Phys. Rev. D 101, 081502 (2020), 2019 Gravitational wave signals from compact astrophysical sources such as those observed by LIGO and Virgo require a high-accuracy, theory-based waveform model for the analysis of the recorded signal. Current inspiral-merger-ringdown models are calibrated only up to moderate mass ratios, thereby limiting their applicability to signals from high-mass ratio ...

Dependence of the ratio of total to visible mass on observable properties of SDSS MaNGA galaxies [PDF]
(2022) ApJ, 925 (2): 127-141, 2020 Using spectroscopic observations from the SDSS MaNGA DR15, we study the relationships between the ratio of total to visible mass and various parameters characterizing the evolution and environment of the galaxies in this survey. Measuring the rotation curve with the relative velocities of the H-alpha emission line across the galaxy's surface, we ...

Parametric Analysis of an Energy-Harvesting Device for a Riser Based on Vortex-Induced Vibrations
Energies, 2020 An energy-harvesting device for a riser based on vortex-induced vibration is proposed to overcome the power supply problem for a marine deep-water riser-monitoring device.

The Smallest Mass Ratio Young Star Spectroscopic Binaries [PDF]
, 2002 Using high resolution near-infrared spectroscopy with the Keck telescope, we have detected the radial velocity signatures of the cool secondary components in four optically identified pre-main-sequence, single-lined spectroscopic binaries.

On the evolution of the black hole: spheroid mass ratio [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 AbstractWe present the results of a study which uses the 3CRR sample of radio‐loud active galactic nuclei (AGN) to investigate the evolution of the black‐hole:spheroid relation in the most massive early‐type galaxies from 0 < z < 2. Radioloud unification is exploited to obtain virial (line‐width) black‐hole mass estimates from the 3CRR quasars ...

Considerations on similarity condition of wing deformation in flapping for model and mosquito wings
Journal of Biomechanical Science and Engineering, 2019 In our previous paper, to simulate mosquito flapping flight, experiments were performed using a wing model, which had n-times (n=10) enlarged shape of the mosquito wing and was made of deformable elastic material.
