We discuss the interpretation of distortions to stellar spectral lines with particular attention to line bisectors in the presence of an orbiting planetary companion. We present a simple model whereby light reflected by the companion can cause temporal variations to the observed line profiles. These distortions have a characteristic signature depending on the inclination angle of the system. Fo...

The photometric U orbital variations of the symbiotic binary AG Dra, caused by occultation of a bright gaseous region by the K giant in this system, are used to derive the emission from the circumbinary nebula, that is supposed to be generated by the cool giant’s wind. Assuming spherical symmetry and constant expansion velocity for the wind, and that the giant has the same intrinsic continuum e...

It is shown in [BoO] that any two genus one Heegaard splittings of the same manifold (typically a lens space) are isotopic. On the other hand, it is shown in [BCZ] that certain Seifert manifolds have distinct genus two Heegaard splittings (see also Section 3 here). In [RS] we presented a technique for comparing Heegaard splittings of the same manifold and, using this technique, derive the Bonah...

We obtained time-series spectroscopy of the G0 subgiant η Boo in an attempt to confirm the solar-like oscillations reported by Kjeldsen et al. (1995). We recorded 1843 spectra over six consecutive nights with the Nordic Optical Telescope, which we used to measure equivalent widths of strong temperature-sensitive lines. We also measured velocities from 1989 spectra obtained through an iodine ref...

W view the beam orientation optimization (BOO) problem in intensity modulated radiation therapy (IMRT) treatment planning as a global optimization problem with expensive objective function evaluations. We propose a response surface method that, in contrast with other approaches, allows for the generation of problem data only for promising beam orientations as the algorithm progresses. This enab...

Absolute dimensions of eclipsing binaries. XXVI. ABSTRACT Context. Accurate mass, radius, and abundance determinations from binaries provide important information on stellar evolution, fundamental to central fields in modern astrophysics and cosmology. Aims. We aim to determine absolute dimensions and abundances for the three F-type main-sequence detached eclipsing binaries AD Boo, VZ Hya, and ...

BACKGROUND Cell adhesion molecules (CAMs) are essential for maintaining tissue integrity by regulating intercellular and cell to extracellular matrix interactions. Cadherins and catenins are CAMs that are located on the cell membrane and are important for adherens junction (AJ) function. This study aims to verify if hypercholesterolemic diet (HCD) or bladder outlet obstruction (BOO) promotes st...

We present the photometric analysis of six short-period systems (EI Oct, V336 TrA, NX Boo, V356 PS and V2282 Cyg). This is first these except for TrA. Observations were conducted 27 nights at three observatories in northern southern hemispheres. calculated a new ephemeris each using our minimum times additional literature. The Markov Chain Monte Carlo (MCMC) approach was used to determine eclip...
