Échelle Spectroscopy of the Chemically Peculiar Star Ori F
Rafael Costero, Christine Allen, Alex Ruelas-Mayorga +4
We analyse Échelle spectra of Ori F obtained by us on six nights unevenly distributed along six years; we identify several hundred spectral lines and measure, for the first t…
The reliability of the Titius-Bode relation and its implications for the search for exoplanets
Patricia Lara, Guadalupe Cordero-Tercero, Christine Allen
The major semiaxes of the planets in our Solar System obey a simple geometric progression known as the Titius-Bode Relation (TBR), whose physical origin remains disputed. It has be…
The Importance of Historical Measures for Dynamical Models of the Evolution of Trapezium-type Multiple Systems
Christine Allen, Leonardo J. Sanchez, Alex Ruelas-Mayorga +1
As an illustration of the value of historical measures we present some examples of the dynamical evolution of multiple systems resembling the Orion Trapezium. We constructed models…
Variable stars in Palomar 13; an evaporating globular cluster
M. A. Yepeza, A. Arellano Ferro, K. P. Schroeder +3
We present new CCD photometry of the distant globular cluster Pal 13. Fourier decomposition of the light curves of the three cluster member RRab stars lead to estimations of […
Challenging a Newtonian prediction through Gaia wide binaries
X. Hernandez, R. A. M. Cortés, C. Allen +1
Under Newtonian dynamics, the relative motion of the components of a binary star should follow a Keplerian scaling with separation. Once orientation effects and a distribution of e…
The Dynamical Evolution of Multiple Systems of Trapezium Type
Christine Allen, Alex Ruelas-Mayorga, Leonardo J. Sánchez +1
We have selected archival observational data for several O and B trapezia in the Milky Way. For each of the main components of the trapezia we obtained transverse velocities from t…
