Mass Transfer in Mira-Type Binaries

open access: yesOpen Astronomy, 2012
Detached, symbiotic binaries are generally assumed to interact via Bondi-Hoyle-Littleton (BHL) wind accretion. However, the accretion rates and outflow geometries that result from this mass-transfer mechanism cannot adequately explain the observations of

New Symbiotic Stars Monitored with the Hermes Spectrograph: A Case Study of Orbital Hα Modulation

open access: yesOpen Astronomy, 2012
We present new orbital elements for two symbiotic systems involving a giant of spectral type S, namely V420 Hya and ER Del. These orbital elements are compared with existing elements for S-type binaries and for symbiotic binaries with M-giant primaries ...

Orbital and physical parameters of eclipsing binaries from the ASAS catalogue – XI. CHIRON investigation of long-period binaries* [PDF]

open access: yes, 2020
We present the results of a spectroscopic campaign on eclipsing binaries with long orbital period (P = 20 - 75 d) carried out with the CHIRON spectrograph.

Beyond binaries and before becoming: Reconsidering resistance in UK higher education

open access: yesPRISM, 2021
 Drawing from the tensions within non-representational and human practice perspectives on affect, this paper continues the task of re-conceptualising academic-level resistance in the context of UK higher education.

Multiwavelength SED as a Tool in Understanding Outbursts of Symbiotic Binaries

open access: yesOpen Astronomy, 2012
Symbiotic binaries consist of a few sources of radiation contributing to spectral energy distribution (SED) from hard X-rays to radio wavelengths.

Asteroseismic Analysis of δ Scuti Components of Binary Systems: The Case of KIC 8504570

open access: yesGalaxies, 2020
The present work concerns the Asteroseismology of the Kepler-detached eclipsing binary KIC 8504570. Particularly, it focuses on the pulsational behaviour of the oscillating component of this system and the estimation of its physical parameters in order ...

Reconstructing Historical Light Curves of Symbiotic Stars and Novae

open access: yesOpen Astronomy, 2012
We reconstructed photometric histories of symbiotic stars and novae from direct inspection and measurement of photographic plates preserved at historical archives.

Safety of Daprodustat for the Treatment of Chronic Kidney Disease Anemia: Final Analysis of a Multicenter Postmarketing Surveillance Study in Japan

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This final analysis of a multicenter, prospective postmarketing surveillance study evaluated the safety of daprodustat in patients with chronic kidney disease anemia in routine clinical practice in Japan. Methods Patients who initiated daprodustat between September 2020 and July 2022 were registered.

The Evolution of a Supermassive Retrograde Binary Embedded in an Accretion Disk

open access: yesOpen Astronomy, 2015
In this note we discuss the main results of a study of a massive binary with unequal mass ratio, q, embedded in an accretion disk, with its orbital rotation being opposed to that of the disk.
