Merritt Blvd., Box 9501, Nashville, TN 37209, USA Received 14 February 2013 / Accepted 6 November 2013 ABSTRACT Aims. We model the photometry of RS CVn star σ Geminorum to obtain new information on the changes of the surface starspot distribution, that is, activity cycles, differential rotation, and active longitudes. Methods. We used the previously published continuous period search (CPS) method to analyse V-band differential photometry ob- tained between the years 1987 and 2010 with the T3 0.4 m Automated Telescope at the Fairborn Observatory. The CPS method divides data into short subsets and then models the light-curves with Fourier-models of variable orders and provides estimates of the mean magnitude, amplitude, period, and light-curve minima. These light-curve parameters are then analysed for signs of activity cycles, differential rotation and active longitudes. d Results. We confirm the presence of two previously found stable active longitudes, synchronised with the orbital period Porb = 19.60, and found eight events where the active longitudes are disrupted. The epochs of the primary light-curve minima rotate with a shorter d period Pmin,1 = 19.47 than the orbital motion. -
THE RS CANUM VENATICORUM STARS 1. Introduction
THE RS CANUM VENATICORUM STARS MARCELLO RODONÖ Istituto di Astronomia, Universita degli Studi, and Osservatorio Astrofisico, 1-95125 Catania, Italy ABSTRACT. The picture emerging from recent studies of RS CVn-type systems indicates the presence of very active stars showing typical solar-like activity phenomena, such as spots and flares, and possibly mutual interactions. The binary nature of RS CVns is certainly important in enforcing high stellar rotation rates, but the actual clue to the understanding of the intrinsic variability of the component stars resides in their internal structure, where the appropriate physical conditions are met for the generation and inten- sification of strong magnetic fields, as prescribed by the aw-dynamo models. The most significant results have been derived from multi-wavelength, coordinated observations and long-term monitoring programs. Recent highlights include: a) the mapping of compact atmospheric structures at various temperature regimes by light curve modelling and spectral (Doppler) imaging techniques; 6) clear evidence of long-term activity cycles on RS CVn and other types of interacting binaries; c) the detection and measurement of surface magnetic fields, as derived from the differential Zeeman splitting of spectral lines. These results clearly demonstrate that the study of RS CVn stars can play a very fundamental role in the understanding of basic stellar physics, as well as in interpreting the characteristic variability of interacting binaries. 1. Introduction Since the discovery of the characteristic outside-of-eclipse photometric or distortion wave on the light curve of the RS CVn system at Catania Observatory (Rodono 1965, Chisari and Lacona 1965, Catalano and Rodono 1967) and the identification of the new class of binaries named after RS CVn (Oliver 1974, Hall 1976), a powerful astrophysical laboratory for the study of solar-like activity on other stars, in addition to the Sun, has become available. -
The RS Canum Venaticorum Binary HD 116204
J. Astrophys. Astr. (1987) 8, 389–395 The RS Canum Venaticorum Binary HD 116204 S. Mohin & Α. V. Raveendran Indian Institute of Astrophysics, Bangalore 560034 Received 1987 July 30; accepted 1987 November 13 Abstract. BV photometry of HD 116204 obtained on 57 nights during 1983–84, 1984–85 and 1986–87 observing season is presented. A photo- metric period of 21.9 ± 0.2 d and a mean (B – V)= 1.196 ± 0.010 are ob- tained. It is suggested that the binary HD 116204 has a mass ratio close to unity. Attempts are needed to detect the spectrum of secondary. Key words: BV photometry—HD 116204—RS CVn systems 1. Introduction A preliminary inspection of moderate-dispersion objective prism survey by Bidelman (1983) has shown the K2-type HD 116204 to be a Ca II emission star. In 1984 January we started observations of this star as part of a programme to study the photometric behaviour and chromospheric activity of late-type emission-line binaries. From the U B V photometry of this star its variability with a 21.7 day period has since been reported by Boyd, Genet & Hall (1984). Here we report on our BV photometric observations of HD 116204. 2. Observations HD 1 16204 was observed on a total of 57 nights during the three observing seasons 1983–84 (13 nights), 1984–85 (7 nights), and 1986–87 (37 nights) with the 34-cm reflector of Vainu Bappu Observatory, Kavalur, using standard Β and V filters. The comparison stars were HD 116494 (spectral type G5) and HD 115968 (spectral type K0). -
Clinical Photography Manual by Kris Chmielewski Introduction
Clinical Photography Manual by Kris Chmielewski Introduction Dental photography requires basic knowledge about general photographic rules, but also proper equipment and a digital workflow are important. In this manual you will find practical information about recommended equipment, settings, and accessories. For success with clinical photo documentation, consistency is the key. The shots and views presented here are intended as recommendations. While documenting cases, it is very important to compose the images in a consistent manner, so that the results or stages of the treatment can easily be compared. Don’t stop documenting if a failure occurs. It’s even more important to document such cases because of their high educational value. Dr. Kris Chmielewski, DDS, MSc Educational Director of Dental Photo Master About the author Kris Chmielewski is a dentist and professional photographer. Highly experienced in implantology and esthetic dentistry, he has more than 20 years experience with dental photography.

SAIT Polytechnic Journalism Program – 2012 / 2013 RECOMMENDED CAMERAS LIST for PHOTOJOURNALISM
SAIT Polytechnic Journalism Program – 2012 / 2013 RECOMMENDED CAMERAS LIST FOR PHOTOJOURNALISM So, what does a typical photojournalist carry? A typical photojournalist will usually carry two (sometimes more) camera bodies, a selection of high quality lenses, at least two flash units, wireless transmitters, and a wide variety of other accessories. For the first year journalism student, however, this would be far too cost- prohibitive to require all of this equipment. We only require students to purchase the absolute minimum - one camera, one lens, one flash, and a selection of smaller accessories (please see the Equipment & Supplies List document). However, students should be aware that to pursue photojournalism as a means of making a living, a significant outlay of money for equipment purchases and upgrades will be required throughout your career. But, you must also keep in mind that unless you are independently wealthy, there are few photojournalists working today who were able to purchase all of their equipment in the early stages (especially their college years) of their career. If you are concerned about the costs of entry into this industry, please take heart – equipment can be acquired over a period of time. What Camera Should You Choose? For serious professional photojournalists, Canon and Nikon are the two main brands that cater to the professional market. Keep in mind that if you are serious about pursuing the photojournalism major in second year, you will need to have the appropriate equipment to handle the rigors of the profession. CANON: all models below have video capability (which is mandatory for our course) • Lower-end, entry level DSLRs… Canon EOS Rebel series cameras… Models include the T2i; T3; T3i; T4i. -

An Investigation of GSC 02038-00293, a Suspected RS Cvn Star, Using CCD Photometry
An investigation of GSC 02038-00293, a suspected RS CVn star, using CCD photometry. Alastair Bruce, Stewart Cruickshank, Tony Rodda and Mark Salisbury. (Members of the 2010 Open University Module S382 Undergraduate Programme). Abstract We present the results of differential, time series photometry for GSC 02038-00293, a suspected RS CVn binary, using data collected with the Open University's PIRATE robotic telescope located at the Observatori Astronomic de Mallorca between 10 May and 13 June 2010. A full orbital period cycle in the V band and partial cycle of B and R bands were obtained for GSC 02038-00293 showing an orbital period of 0.4955 +/- 0.0001 days. This period is in close agreement with that of previously published values but significantly different to that found by the All Sky Automated Survey of 0.330973 days. We suggest GSC 02038-00293 is a short period eclipsing RS CVn star and from our data alone we calculate an ephemeris of JD 2455327.614 + 0.4955(1) x E. We also find that the previously observed six to eight year cycle of star spot activity which accounts for the behaviour of the secondary minimum is closer to six years and that there is detectable reddening at both minima. Introduction We have undertaken a differential photometric study of GSC 02038-00293 known to display short period modulations in optical magnitude and to emit X-rays with a view to characterize the physical properties of this source. The target is located at RA 16h 02m 48.22s and Dec +25° 20’ 38.2’’ in the constellation of Serpens Caput. -
