From Global to Spatially Resolved in Low-Redshift Galaxies

Abstract: Our understanding of the structure, composition and evolution of galaxies has strongly improved in the last decades, mostly due to new results based on large spectroscopic and imaging surveys. In particular, the nature of ionized gas, its ionization mechanism

A Pulsating Flare Star in the New Planetary System: KOI-258
E. Yoldaş H. A. Dal

Abstract: We present findings about the nature of KOI-258. Its temperature was found to be 6500 ± 200 K from its spectrum, which also indicates that the target is a single main sequence star despite the existence of a radial velocity variation with a small amplitude. C

Comparative Analysis of Sky Quality and Meteorological Variables During the Total Lunar Eclipse on 14-15 April 2014 and their Effect on Qualitative Measurements of the Bortle Scale
C. Góez Therán S. Vargas Domínguez

Abstract: A total lunar eclipse plausibly has an influence on the variation of some environmental physical parameters, specifically on the conditions of the sky brightness, humidity and temperature. During the eclipse on 14th-15th April 2014, these parameters were meas

Exploring the Nature of Compact Radio Sources Associated to UCHII Regions

Abstract: We present Very Large Array 7 mm continuum observations of four ultracompact (UC) HII regions, observed previously at 1.3 cm, in order to investigate the nature of the compact radio sources associated with these regions. We detect a total of seven compact rad

A Study of the Time Variability and Line Profile Variations of κ Dra

Abstract: We present a spectroscopic analysis of the bright Be star κDra. Two independent sets of radial velocity (RV) measurements were obtained by direct measurement and using a line profile disentangling technique. By combining solutions from codes FOTEL and KOREL,

Periodicity Detection in AGN with the Boosted Tree Method
S. B. Soltau L. C. L. Botti

Abstract: We apply a machine learning algorithm called XGBoost to explore the periodicity of two radio sources: PKS 1921-293 (OV 236) and PKS 2200+420 (BL Lac), both radio frequency datasets obtained from University of Michigan Radio Astronomy Observatory (UMRAO), at 4

Kepler Planetary Systems: Doppler Beaming Effect Significance
H. Barbier E. López

Abstract: In the present work, in order to estimate the semi-amplitude of the radial velocity, we evaluate the contribution of the Doppler beaming effect to the phase curves of the all confirmed extrasolar planets (2776, September 2019), observed so far by the Kepler t

X-Ray Flux and Spectral Variability of BL Lacertae Objects Mrk 421, Mrk 501, and 1ES1426+428 with Suzaku Satellite

Abstract: We present a detailed spectral study of Suzaku observations of three blazars (Mrk 421, Mrk 501, and 1ES1426+428). The X-ray properties of our sample are derived by extracting the BL Lacertae sample spectra, and fitted by five models. The fit was in the soft X

Asymptotic internal working surfaces of periodically variable jets

Abstract: We present a derivation based on the “center of mass formalism” of the asymptotic behaviour of internal working surfaces produced in a variable Herbig- Haro (HH) jet. We obtain the general solution for an arbitrary periodic ejection time-variability, and then

Analytic Solutions for Truncated Plasmons
J. Cantó A. C. Raga

Abstract: We present a new plasmon model for a cometary clump moving supersonically in an environment with a non-zero gas pressure. We find that the environmental pressure produces a cutoff in the wings of the cometary clump, therefore resulting in quite \stubby" plasm
