Die Neigung der Erdachse gegenüber der Ebene der Erdbewegung um die Sonne (Ekliptik) beträgt derzeit 23° 26' 23'', die gedachte Verlängerung der Erdachse ist zum Himmelspol (derzeit Polarstern, Polaris, α UMi) gerichtet, Erdachsenneigung und Orientierung der Erdachsenneigung im Raum unterliegen langfristigen Variationen. Vergleichbar einer Kreiselbewegung bewegt sich die schräg zur Ekliptik stehende Erdachse in einem Zeitraum von etwa 25.700 - 25.800 Jahren einmal um die senkrecht auf der Ebene der Ekliptik stehenden Achse durch den Erdmittelpunkt. In dieser auch als Zyklus der Präzession bezeichneten Präzessionsperiode (lat. praecedo – vorangehen) wandert der Frühlingspunkt einmal durch alle Tierkreissternbilder. Dieser Zyklus der Präzession wird auch Das Große Jahr, Platonisches Jahr oder Weltjahr genannt. In der Jetztzeit kreuzt die Ekliptik in den Fischen (Pisces, Psc, , 14/88, 889 deg2) den Himmelsäquator. Dieser Kreuzungspunkt, der Frühlingspunkt, ist der Ursprung der wichtigsten astronomischen Koordinatensysteme am Sternenhimmel. Lag in der Antike der Frühlingspunkt (23.03.), der Schnittpunkt des Himmelsäquators mit der Ekliptik, im Widder (Aries, Ari, ), wanderte dieser der Präzessionsbewegung der Erdachse wegen um Christi Geburt zur Grenze zwischen Widder und Fische und verlagerte sich in der Jetztzeit in das Sternbild Fische. Heute durchläuft die Sonne alljährlich vom 12.03. - 19.04. die Fische, vom 19.04. - 14.05. das Sternbild des Widders. Im Jahre 2597 wird der Frühlingspunkt, heutige Sternbildgrenzen vorausgesetzt, in das Sternbild Wassermann (Aquarius, Aqr, ) wandern.

Received 2019 April 22; in original form 2019 March 20 ABSTRACT In this work we revisit the issue of the rotation speed of the spiral arms and the location of the corotation radius of our Galaxy. This research was performed using ho- mogeneous data set of young open clusters (age < 50 Myr) determined from Gaia DR2 data. The stellar astrometric membership were determined using proper motions and parallaxes, taking into account the full covariance matrix. The distance, age, reddening and metallicity of the clusters were determined by our non subjective multidimensional global optimization tool to fit theoretical isochrones to Gaia DR2 photometric data. The rotation speed of the arms is obtained from the relation between age and angu- lar distance of the birthplace of the clusters to the present-day position of the arms. Using the clusters belonging to the Sagittarius-Carina, Local and Perseus arms, and −1 adopting the Galactic parameters R0 = 8.3 kpc and V0 = 240 kms , we determine a pattern speed of 28.2 ± 2.1 kms−1 kpc−1, with no difference between the arms.

Bordeaux, CNRS, UMR 5804, 33615 Pessac, France Received date / Accepted date ABSTRACT Context. The Tycho-Gaia Astrometric Solution (TGAS) subset of the first Gaia catalogue contains an unprecedented sample of proper motions and parallaxes for two million stars brighter than G ∼ 12 mag. Aims. We take advantage of the full astrometric solution available for those stars to identify the members of known open clusters and compute mean cluster parameters using either TGAS or the fourth U.S. Naval Observatory CCD Astrograph Catalog (UCAC4) proper motions, and TGAS parallaxes. Methods. We apply an unsupervised membership assignment procedure to select high probability cluster members, we use a Bayesian/Markov Chain Monte Carlo technique to fit stellar isochrones to the observed 2MASS JHKS magnitudes of the member stars and derive cluster parameters (age, metallicity, extinction, distance modulus), and we combine TGAS data with spectroscopic radial velocities to compute full Galactic orbits.

Received 2019 November 13; in original form 2019 July 04 ABSTRACT Several recent studies have shown that the Vela OB2 region hosts a complex constel- lation of sub-populations with ages in the range 10 to 50 Myr. Such populations might represent the best example of the outcome of clustered star formation in Giant Molec- ular clouds (GMC). We use Gaia DR2 data over an area of 40 deg radius around the open cluster Collinder 135 to extend the study of the stellar populations of the Vela OB2 region over an area of several hundreds of parsecs on sky. Detailed clustering al- gorithms combined with the exquisite astrometric quality of the GAIA catalogue allow us to detect a new cluster named BBJ 1 that shows the same age as NGC 2547 (30 to 35 Myr), but located at a distance of 260 pc from it.

  • Parallaxes and Proper Motions for 20 Open Clusters As Based on the New Hipparcos Catalogue
    A&A 497, 209–242 (2009) Astronomy DOI: 10.1051/0004-6361/200811382 & c ESO 2009 Astrophysics Parallaxes and proper motions for 20 open clusters as based on the new Hipparcos catalogue F. van Leeuwen Institute of Astronomy, Madingley Road, Cambridge, UK e-mail: [email protected] Received 19 November 2008 / Accepted 2 February 2009 ABSTRACT Context. A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming that the accu- racies for nearly all stars brighter than magnitude Hp = 8 are improved, by up to a factor 4, compared to the original catalogue. As correlations between the underlying abscissa residuals have also been reduced by more than an order of magnitude to an insignificant level, our ability to determine reliable parallaxes and proper motions for open clusters should be improved. Aims. The new Hipparcos astrometric catalogue is used to derive mean parallax and proper motion estimates for 20 open clusters. The HR-diagrams of the nearest clusters are compared and combined to provide future input to sets of observational isochrones. Methods. Three different methods are applied, according to the proximity of the cluster, to compensate, where needed, for projection effects, spread in position along the line of sight, and the internal velocity dispersion of the cluster stars. Results. The new parallaxes have accuracies between 2 and 2.5 times higher than what had been derived from the original Hipparcos catalogue. At least two to three groups of clusters, mostly of similar ages, are observed to each occupy their own specific space in the HR diagram.

We demonstrate that reliable photometric distances of stellar clusters, and more generally of stars, can be obtained using pseudomagnitudes and rough spectral type without having to correct for visual absorption. Methods. We determine the mean absolute pseudomagnitude of all spectral (sub)types between B and K. Distances are computed from the difference between the star’s observed pseudomagnitude and its spectral type’s absolute pseudomagnitude. We compare the distances of 30 open clusters thus derived against the distances derived from TGAS parallaxes. Results. Our computed distances, up to distance modulus 12, agree within 0.1 mag rms with those obtained from TGAS parallaxes, proving excellent distance estimates. We show additionally that there are actually two markedly different distances in the cluster NGC 2264. Conclusions. We suggest that the pseudomagnitude distance estimation method, which is easy to perform, can be routinely used in all large-scale surveys where statistical distances on a set of stars, such as an open cluster, are required.
