Les equations aux variations et la 11e integrale du probleme desN corps
Let H=T(p)−U(q) the Hamiltonian of the N -body problem in cartesian coordinates. In his ‘Nouvelles Méthodes de la Mécanique Céleste’ (tome 1, p. 172)...

Mouvement d'un satellite à rotation lente dans le champ magnétique terrestre
The movement, in the Earth's magnetic field, of a magnetized satellite around its center of gravity is investigated. The magnetic moment is of the...

Theorie analytique programmee de la libration physique de la lune
The rotation of the Moon about its center of mass, taking into account the orbital motion, is treated analytically. A Hamiltonian theory is developed...

Sur une generalisation des equations lagrangiennes permettant une extension de la transformation KS
This paper is composed of two parts, the first one established by M. Langlois, the other one by L. Losco. First a study of Poincaré's equations is...

La distance de la Nova Delphini 1967
The good agreement found between the observed flux of radio emission of the Nova Delphini 1967 and that calculated theoretically enables us to deduce...

Sur de nouvelles séries pour le problème de masses critiques de Routh dans le problème restreint plan des trois corps
The planar restricted 3-body problem, linearized in the neighborhood of Lagrangian equilibria L 4 and L 5 , has in general two distinct eigenvalues and...

Sur la recherche des mouvements stationnaires dans les systèmes ayant des variables cycliques
A ‘constrained system’ is associated with a mechanical system having cyclic coordinates. We prove that the set of steady motions of this mechanical...

Les bulles chromospheriques
Nous étudions des structures chromosphériques qui ont été identifiées sur des filtrogrammes pris au bord du disque solaire dans la raie Hα, et que...

Un formulaire pour le calcul des perturbations d'ordres élevés dans les problèmes planétaires
The authors present formulas in compact form for constructing high order planetary perturbations with respect to the disturbing masses. They have...

Théorie analytique programmée du mouvement des satellites artificiels sous l'action gravitationnelle de la terre
In the analytical theory presented here, the developments of the first, second and third orders, different from those given by the direct solution of...

Problème restreint des trois corps appliqué à un gyrostat
This paper is concerned with an extension of the classical restricted problem of three bodies when the smallest body is not considered to be a point...

Population théorique des sous niveaux Zeeman relatifs à la raie 5303 Å de Fe xiv
We give here under compact tables the relative population of the six first levels arising from the hyperfine structure of Fe xiv . These populations...

Remarques sur l'utilisation des profils lunaires pour la reduction des observations d'occultations
It is shown that a rigourous determination of the argument in the limb charts of the Moon leads to a limb correction which, in some cases, may differ...

Etude de l'eclipse solaire partielle du 25 Fevrier, 1971 au Pic du Midi
The scattering in the neighbourhood of the Sun is investigated on photographs taken in Pic-du-Midi Observatory during the partial solar eclipse of...

Liste et classification d'étoiles M, C et à émission nouvelles
We present a new list of 156 M, C or emission line stars discovered on objective-prism plates taken at Haute Provence Observatory. The good spectra...

Evolution du spectre de la Nova Delphini 1967 en 1971 et 1972
Continued spectroscopic observations of Nova Del 67 during 1971 and 1972 show a general decrease of the nebular and coronal emission with respect to...

Étude du système AX Mon
We have divided this investigation into four main parts.
In the first part, we study the ways in which the envelope affects the composition and the...

Comparaison de catalogues de crateres lunaires
The systematic part of the differences between positions in crater catalogues is expanded into spherical harmonics. The application of the χ 2 test...

La loi de danjon et les eruptions volcaniques
Danjon's law describing the variations of the luminosity of lunar eclipses during the 11 year cycle of solar activity has been verified in 7 cases...

Evolution d'attitude d'un satellite dans le champ magnetique terrestre
A possible representation of the motion of a satellite about its centre of mass is investigated. The satellite's magnetic moment is of the order of...
