The origin of the planetary nebula M 1-16. A morphokinematic and chemical analysis
M. A. Gómez-Muñoz, R. Vázquez, L. Sabin +4
We investigated the origin of the Planetary Nebula (PN) M 1-16 using narrow-band optical imaging, and high- and low-resolution optical spectra to perform a detailed morpho-kinemati…
The study of eleven contact binaries with mass ratios less than 0.1
Xin-Yi Liu, Kai Li, Raul Michel +6
Multi-band photometric observations of eleven totally eclipsing contact binaries were carried out. Applying the Wilson-Devinney program, photometric solutions were obtained. There…
The first photometric investigation and spectroscopic analysis of two contact binaries: ASAS J124343+1531.7 and LINEAR 2323566
Qiqi Xia, Raul Michel, Kai Li +1
The multi-color passband CCD light curves of ASAS J124343+1531.7 and LINEAR 2323566 were first obtained by the 0.84-m Ritchey-Chrétien telescope with follow up observations by the…
New radial velocity observations of AH Her: evidence for material outside the tidal radius
J. Echevarría, J. V. Hernández Santisteban, O. Segura Montero +7
Spectroscopic observations of AH Herculis during a deep quiescent state are put forward. We found the object in a rare long minima, allowing us to derive accurately the semi-amplit…
The first light curve modeling and orbital period change investigation of nine contact binaries around the short period cut-off
Kai Li, Chun-Hwey Kim, Qi-Qi Xia +5
In this paper, we present the first light curve synthesis and orbital period change analysis of nine contact binaries around the short period limit. It is found that all these syst…
Photometric light curve solutions of three ultra-short period eclipsing binaries
F. Acerbi, R. Michel, C. Barani +2
We present the results of our study of the eclipsing binary systems CSS J112237.1+395219, LINEAR 1286561 and LINEAR 2602707 based on new CCD , , and complete ligh…
