Properties of the Photometric Components of Lenticular Galaxies [PDF]
Advances in Astronomy, 2012 After almost one century since their definition, the origin of lenticular galaxies is still a matter of debate. Several formation processes have been proposed in order to explain the wide variety of their observational properties.

Thick disks of lenticular galaxies - 3D-photometric thin/thick disk decomposition of eight edge-on S0 galaxies [PDF]
Astronomy & Astrophysics, 2004 Thick disks are faint and extended stellar components found around several disk galaxies including our Milky Way. The Milky Way thick disk, the only one studied in detail, contains mostly old disk stars (~10 Gyr), so that thick disks are likely to trace the early stages of disk evolution.

Properties of stellar populations in isolated lenticular galaxies [PDF]
Astrophysical Bulletin, 2014 In this paper we present the results of long-slit spectral observations for a sample of isolated lenticular galaxies, made with the SCORPIO and SCORPIO-2 spectrographs of the 6-meter BTA telescope of the SAO RAS. By applying full spectral fitting technique using the stellar population evolutionary synthesis models, we have measured the radial profiles ...

Abundant Molecular Gas in the Central Region of Lenticular Galaxy PGC 39535 [PDF]
The Astrophysical JournalLenticular galaxies (S0s) in the local Universe are generally absent of recent star formation and lack molecular gas. In this paper, we investigate one massive ( M _* ∼ 5 × 10 ^10 M _⊙ ) star-forming S0, PGC 39535, with the Northern Extended Millimeter ...

A slow bar in the lenticular barred galaxy NGC 4277 [PDF]
Astronomy & Astrophysics, 2022 Aims. We characterised the properties of the bar hosted in lenticular galaxy NGC4277, which is located behind the Virgo cluster. Methods. We measured the bar length and strength from the surface photometry obtained from the broad-band imaging of the ...

Inner structure of the lenticular galaxy NGC 3384 [PDF]
Monthly Notices of the Royal Astronomical Society, 1984 La region interne de la galaxie lenticulaire NGC 3384 presente une structure complexe. La haute resolution (FWHM≃0,7 arc sec) obtenue pour cette etude photometrique permet de montrer que la faible structure allongee croisant le bulbe perpendiculairement a l'axe principal de la galaxie n'est probablement pas une barre, mais un petit anneau polaire de ...

Inner Polar Rings in Regular Lenticular Galaxies [PDF]
The Astronomical Journal, 2004 We have investigated a sample of S0 galaxies, mostly with circumnuclear dust lanes orthogonal to their major axes, chosen from Hubble Space Telescope Wide Field Planetary Camera 2 images. Two-dimensional spectroscopy undertaken with the Multipupil Fiber Spectrograph of the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of
