FCAPT uvby Photometry of the mCP Stars HD 16545, HD 93226, HR 7575, and HR 8206

DOI: 10.1086/521962 Bibcode: 2007PASP..119..980A

Adelman, Saul J.

The Four College Automated Photoelectric Telescope (FCAPT) obtained differential Strömgren uvby observations of the magnetic CP (mCP) stars HD 16545, HD 93226, HR 7575, and HR 8206. These are the first reported from the FCAPT. HD 16545, with its largest amplitudes (0.06 mag) being those in v and in b, has a period of 1.61926 days, close to its per…

Preliminary results on the fundamental parameters of the eclipsing binary V398 Lacertae

DOI: 10.1002/asna.200610755 Bibcode: 2007AN....328..536C

Frasca, A.; Soydugan, F.; Çakırlı, Ö. +2 more

The Hipparcos Space Astrometry Mission photometric observations of V398 Lac, led to the discovery of its variability, allowing to classify it as an eclipsing binary with an orbital period of about 5.4 days. This prompted us to acquire high-resolution échelle spectra with the aim of performing accurate radial velocity measurements and to determine …

Development dynamics of intense solar proton flares

DOI: 10.1134/S1063773707090058 Bibcode: 2007AstL...33..615S

Zimovets, I. V.; Struminsky, A. B.

We consider the relationship of electromagnetic radiation in the three most intense flares of solar cycle 23, more specifically, those of October 28, 2003, January 20, 2005, and September 7, 2005, to the acceleration and release of protons into interplanetary space. The impulsive phase of these flares lasted ∼ 20 min and consisted of at least thre…

Simulated Annealing and Bayesian Posterior Distribution Analysis Applied to Spectral Emission Line Fitting

DOI: 10.1007/s11207-007-0358-8 Bibcode: 2007SoPh..243..237I

Ireland, Jack

Spectral-line fitting problems are extremely common in all remote-sensing disciplines, solar physics included. Spectra in solar physics are frequently parameterized by using a model for the background and the emission lines, and various computational techniques are used to find values to the parameters given the data. However, the most commonly-us…

Initial mass function effects on the colour evolution of disk galaxies

DOI: 10.1051/0004-6361:20066057 Bibcode: 2007A&A...465..417W

Samland, M.; Kautsch, S. J.; Westera, P. +2 more

Aims:In this work, we want to find out if the IMF can be determined from colour images, integrated colours, or mass-to-light ratios, especially at high redshift, where galaxies cannot be resolved into individual stars, which would enable us to investigate dependencies of the IMF on cosmological epoch.
Methods: We use chemo-dynamical models to …

The Effect of Proton Temperature Anisotropy on the Electron Heat Flux Dissipation in Solar Coronal Holes

DOI: 10.1086/520044 Bibcode: 2007ApJ...666..486M

Markovskii, S. A.

A possible source of the ion cyclotron waves that energize the protons in the fast solar wind is the electron heat flux launched by reconnection events at the base of coronal holes. A strong enough heat flux becomes unstable and generates cyclotron waves that interact with the protons. When the protons are energized via the cyclotron resonance, th…

Identification of a Peculiar Radio Source in the Aftermath of Large Coronal Mass Ejection Events

DOI: 10.1086/512607 Bibcode: 2007ApJ...656L.105V

Vourlidas, Angelos; Démoulin, Pascal; Hoang, Sang +1 more

We report the discovery of a new radio feature associated with coronal mass ejection (CME) events. The feature is a low-frequency (<1 MHz), relatively wide (~300 kHz) continuum that appears just after the main phase of the eruptive event, lasts for several hours, and exhibits a slow negative frequency drift. So far, we have identified this radi…
