In the short talk on next Monday, I will introduce the following paper. "A solar-like magnetic cycle on the mature K-dwarf 61 Cygni A (HD 201091)" Boro Saikia et al. 2016, A&A, 594, 29 http://adsabs.harvard.edu/abs/2016A%26A...594A..29B This paper reports the first detection of a cool star, apart from the Sun, where the magnetic cycle (polarity reversal etc) is in phase with its chromospheric cycle (Ca II intensity changes), on the basis of 8-year spectropolarimetric monitoring observations. |
5/1 | S.Ueno | In the tomorrow's solar seminar, I plan to talk about the following two things. 1) Introduction of the theme of Mr. Kaiho's DST-observation in last week: According to Ishii-san, Director Shibata requested that contents of recent DST observations should be introduced in the solar seminar. So, I received Mr. Kaiho's presentation file for the seminar on Apr-25. I will briefly introduce it again for people who could not attend his seminar. 2) Report of conference about Chinese future ground-based solar telescopes: When we visited Fuxian Solar Observatory in last December, I attended the conference about Chinese future solar telescopes in Kunming. In this conference, the Chinese Giant Solar Telescope (CGST) and 2.5 m solar and stellar telescope (ISMART) were mainly treated. I will report outline of this conference. | 5/8 | K.Hirose | 5/8 | A.Kawamura | Statistical Characteristics of Solar cycle 23 & Newly Found Aurora Picture (of Solar Cycle 19) | 5/15 | U.Kou | Statistical Characteristics of Solar cycle 23 & Newly Found Aurora Picture (of Solar Cycle 19) | Today I will have a brief introduce of Title: Magnetic Field and Plasma Diagnostics from Coordiated Prominence Observations Author: B. Schmieder et. al Link: http://adsabs.harvard.edu/abs/2016ASPC..504..119S Abstract: This paper studies the temperature, density and flow velocities of the prominence from a statistical point of view by combining the measurements from THEMIS, IRIS, HINODE/EIS and Meudon Solar Tower. They are aiming to answer the following question: 1. what is the general direction of the magnetic field in prominences? 2. are prominences in a weak environment field dominated by gas pressure? 3. if there are substantial velocities to maintain vertical rotation structures, as has been suggested for tornado-like prominences. | 5/15 | S.Nagata | 5/22 | 5/29 | K.Namekata | 5/29 | S.Ninomiya | 6/5 | D.Cabezas | In tomorrow's seminar as a short talk, I will introduce the paper by Kleint et al. (2015) entitled as: "The fast filament eruption leading to the X-flare on 2014 March 29" http://adsabs.harvard.edu/abs/2015ApJ...806....9K | 6/5 | T.Anan | Which spectral line is good for future Japanese space missions? | I would like to talk about development of simultaneous multi-spectral windows spectropolarimetry of the Domeless Solar Telescope at Hida Observatory to select which spectral line is good for future Japanese space missions. At the end of presentation, I would like to discuss with you science objectives what you want to study using the polarimetry. | 6/12 | K.Otsuji | Which spectral line is good for future Japanese space missions? | In next monday's seminar as a short talk, I will introduce the papers shown below: "On HMI solar oblateness during solar cycle 24 and impact of the space environment on results" Meftah, M.; Hauchecorne, A.; Bush, R. I.; Irbah, A.
