We present a model for the local system of gas and stars that we associate essentially with Gould's Belt, the Sirius supercluster, and the Local arm. We consider that these subsystems were formed in different epochs within a supercloud that was initially moving almost ballistically in the Galactic field until an encounter with a major spiral arm started a braking process. The stars of older generations, i.e., the Sirius supercluster, tended to conserve the kinematics of the prebraking phase of… 

The hypothesis of the local supercloud and the nearby moving groups of stars

The velocity distribution of stars in the solar neighbourhood can be globally characterized by the presence of two stellar streams (I and II). Stream I contains kinematic substructures, named moving

Capture of field stars by giant interstellar clouds: the formation of moving stellar groups

In the solar neighbourhood, there are moving groups of stars with similar ages and others of stars with heterogeneous ages as the field stars. To explain these facts, we have constructed a simple

The high-velocity clouds and the Magellanic Clouds

From an analysis of the sky and velocity distributions of the high-velocity clouds (HVCs) we show that the majority of the HVCs has a common origin. We conclude that the HVCs surround the Galaxy,

A Search for a Globular Cluster whose Passage Through the Galactic Disk Could Induce the Formation of the Gould Belt

The distribution of sites where globular clusters have crossed the Galactic disk during the last 100 million years has been analyzed using the most recent kinematic data for 133 globular clusters

Some Observations Related to the Origin and Evolution of the Local Bubble/Local ISM

I discuss some recent observations of the Local Interstellar medium (ISM) that are related to its history and temperature structure. I focus on three topics: (i) the abundance pattern of interstellar

The interstellar medium in the Upper Cepheus-Cassiopeia region

We have studied the kinematics and spatial distribution of the interstellar gas in the sky region 110° ≤l≤ 135°, 10° ≤ b ≤ 20°, using the extensive Leiden-Dwingeloo Survey of H I emission and the

Abstract The accumulation, compression, and cooling of the ambient interstellar medium (ISM) in large-scale flows powered by OB cluster feedback can drive the production of dense molecular clouds. We

Kinematics of young stars. II. Galactic spiral structure

The young star velocity eld is analysed by means of a galactic model which takes into account solar motion, dierential galactic rotation and spiral arm kinematics. We use two samples of Hipparcos

Kinematic peculiarities of Gould Belt stars

We analyzed the space velocities of Gould Belt stars younger than 125 Myr located at heliocentric distances <650 pc. We determined the rotation and expansion parameters of the Gould Belt by assuming



The Kinematics of Stars Emerging from Expanding Shells: An Analysis of the Gould Belt

Using the available data for nearby stars from the Hipparcos catalog, we derive the velocity ellipsoid of dwarf O-B5.5 stars belonging to the Gould Belt (GB). The resulting vertex deviation for the

The local complex of O and B stars. I - Distribution of stars and interstellar dust

The O-B5 stars, supergiants, young clusters, and associations within 1 kpc of the sun populate two flat systems inclined to each other by 19 to 22 deg. The historical background, statistical

The local complex of O and B stars. II - Kinematics

The observed space velocities of O-B5 stars lying within about 1 kpc of the sun are analyzed. Motions examined include local solar motion, differential galactic rotation, mean peculiar stellar

Terrestrial mass extinctions, cometary impacts and the Sun's motion perpendicular to the galactic plane

Episodes of mass extinctions on the Earth are now strongly suspected to be cyclical1. We report here that our analysis of the data of Raup and Sepkoski1 suggests that the dominant cyclicity in major

Large-Scale Aspects of Star Formation and Galactic Evolution

Star formation in spiral and irregular galaxies often appears to occur in large gas complexes or spiral arm segments with characteristic sizes of the order of a kiloparsec and masses of the order of


Lack of reliable estimates of distances to most of the local dark clouds has, so far, prevented a quantitative study of their kinematics. Using a statistical approach, we have been able to extract

Jupiter's Synchrotron Emission Induced by the Collision of Comet Shoemaker-Levy 9

From July 13 to August 21, 1994, we observed Jupiter at 1420 MHz using one of the 30-m single dishes of the Instituto Argentino de Radioastronomía. After the impact of fragment G, we detected a rapid

On the origin of the Orion and Monoceros molecular cloud complexes

A detailed model for the origin of the Orion and Monoceros cloud complexes is presented, showing that a single high-velocity H I cloud-galaxy collision can explain their main observed features. The

The distribution of nearby stars in phase space mapped by Hipparcos - III. Clustering and streaming among A-F type stars

This paper presents the detailed results obtained in the search of density-velocity inhomogeneities in a volume limited and absolute magnitude limited sample of A-F type dwarfs within 125 parsecs of

The Car–Sgr arm as outlined by superclouds and the grand design of the Galaxy

It is found that H I superclouds are regularly spaced along the very long Car-Sgr arm, the mutual distances being mostly 0.1 and 0.2 in units of the Solar distance to the centre. Such regularity is
