Entrainment factor of individual glitch fractional moment of inertia

Abstract: The superfluid in the inner crust of a neutron star is assumed to be the reservoir of momentum released in a pulsar glitch. Recently, due to crustal entrainment, it appears debatable whether the magnitude of the inner crust is sufficient to contain the superf

A solar mid-infrared telescope

Abstract: We developed a mid infrared (MIR) solar telescope, centered at 10µm. Various optical layouts were analyzed based on computer simulations and a Ritchey-Chretien 6-inches telescope was selected with a plate scale of 2.5′′/mm using a pyroelectric 4 × 16 pixels d

Exact solution for flat scale-invariant cosmology
J. F. Jesus

Abstract: An exact solution for the spatially flat scale-invariant cosmology, recently proposed by Maeder (2017a) is deduced. No deviation from the numerical solution was detected. The exact solution yields transparency for the dynamical equations, and faster cosmologi

Extensive photometry of V1838 Aql during the 2013 superoutburst

Abstract: We present an in-depth photometric study of the 2013 superoutburst of the recently discovered cataclysmic variable V1838 Aql and subsequent photometry near its quiescent state. A careful examination of the development of the superhumps is presented. Our best

Asymmetric shapes of radio recombination lines from ionized stellar winds
R. Ignace

Abstract: Recombination line profile shapes are derived for ionized spherical stellar winds at radio wavelengths. It is assumed that the wind is optically thick owing to free-free opacity. Emission lines of arbitrary optical depth are obtained assuming that the free-fr

Optimal trajectories to Kuiper Belt Objects

Abstract: The present paper searches for transfers from the Earth to three of the Kuiper Belt Objects (KBO): Haumea, Makemake, and Quaoar. These trajectories are obtained considering different possibilities of intermediate planet gravity assists. The model is based on t

Multiwavelength observations of MASTER OT 075353.88+174907.6: a likely superoutburst of a long period dwarf nova system

Abstract: MASTER OT 075353.88+174907.6 was a blue optical transient reported by the MASTER-Net project on 2017 Oct 31. We carried out multiwavelength follow-up observations of this source during its 2017 outburst using Swift and RATIR. The source was found to be javax.

Multicolor study of V1009 Per, a close binary system at the beginning of the overcontact phase, and of CRTS J031642.2+332639, a new binary system in the same field

Abstract: The first multicolor observations and light curve solutions of the eclipsing binary systems V1009 Per and CRTS J031642.2+332639 are presented. Using the 2005 version of the Wilson-Devinney code, both systems are found to be W UMa contact binaries. V1009 Per h

On the chromospheric activity nature of a low-mass close binary: KIC 12004834
E. Yoldaş H. A. Dal

Abstract: We study the nature of the chromospheric activity of an eclipsing binary KIC 12004834, using Kepler data. We analyse the light curve of the system, the sinusoidal variations at out-of-eclipses and detected flare events. The secondary component’s temperature i

An alternative approach to the finger of god in large scale structures
L. Salas I. Cruz-González

Abstract: It is generally accepted that linear theory of growth of structure under gravity produces a squashed structure in the two-point correlation function (2PCF) along the line of sight (LoS). The observed radial spread out structure known as Finger of God (FoG) is

Selection effects and structural symmetries in the orientation based unified scheme
C. C. Onuchukwu A. A. Ubachukwu

Abstract: Using the projected linear size, (D) as an orientation parameter, the arm-length ratio, (Q) and the lobe-luminosity ratio, (R) as asymmetry parameters, we test the FR-II galaxies (Gs) and radio-loud quasar (Qs) unification scheme. Using the median values of o

The HH34 jet/counterjet system at 1.5 and 4.5µm

Abstract: We present a (previously unpublished) 1.5 µm archival HST image of the HH 34 Herbig-Haro jet, in which the northern counterjet is seen at an unprecedented angular resolution of ≈ 0.1′′ (this counterjet had only been imaged previously at lower resolution with
