Magnetic Activity and Orbital Period Study for the Short-period RS CVn–type Eclipsing Binary DV Psc

Qing-feng Pi; Li-yun Zhang; Shao-lan BiORCID; Xianming L. Han; Hong-peng Lu; Qiang Yue; Liu Long; Yan Yan

<jats:title>Abstract</jats:title> <jats:p>Using 27 sets of new multiband photometry light curves acquired from our long-term photometric campaign carried out in the last 5 yr and high-resolution spectroscopic data from seven nights, we analyzed the physical mechanisms of period variation, starspot cycle, optical flares, and chromospheric activities of the eclipsing binary DV Psc. Our updated <jats:italic>O</jats:italic> − <jats:italic>C</jats:italic> diagram covering a period of approximately 20 yr shows an oscillation in its orbital period. This variations might be caused by a third body with an orbital period of 14.58 ± 0.28 yr. There are two active regions of starspots at longitude belts of about 90° and 270°. We obtained its starspot cycles with periods of 3.60 ± 0.03 yr and 3.42 ± 0.02 yr at about 90° and 270°, respectively. Moreover, the magnitude difference of Max. I–Max. II shows cyclic oscillation of 5.15 ± 0.01 yr. During our decade long photometric campaign, we observed DV Psc a total of 326.4 hr, detected 18 outbursts (12 of them have never been reported) with flare energies in the range of (6.62–1106.85) × 10<jats:sup>24</jats:sup> J. The slope of the relationship between the phase of the max flare and spots is 0.842 ± 0.083, implying a correlation between spots and flares. We discovered evidence for a correlation between the rotation period and the activity cycle for the short-period eclipsing binaries. Our high-resolution spectroscopic observations of DV Psc show obvious emissions above continuum in the H<jats:sub> <jats:italic>α</jats:italic> </jats:sub> line and small self-reversal emissions of the Ca <jats:sc>ii</jats:sc> IRT lines.</jats:p>

Discovery of a New Class I Methanol Maser Transition at 266.8 GHz

Xi Chen; Simon P. EllingsenORCID; Zhi-Yuan Ren; Andrej M. Sobolev; Sergey Parfenov; Zhi-Qiang Shen

<jats:title>Abstract</jats:title> <jats:p>We report the detection of a new class I methanol maser candidate from the 5<jats:sub>2</jats:sub>−4<jats:sub>1</jats:sub> <jats:italic>E</jats:italic> transition (266.8 GHz). This methanol transition has been detected toward a nearby high-mass star-forming region G352.630-1.067 (distance ∼0.7 kpc), in Submillimeter Array (SMA) observations. The new candidate transition has a similar spatial distribution as the 4<jats:sub>2</jats:sub>−3<jats:sub>1</jats:sub> <jats:italic>E</jats:italic> (218.4 GHz) and 8<jats:sub>−1</jats:sub>−7<jats:sub>0</jats:sub> <jats:italic>E</jats:italic> (229.7 GHz) transitions, which are known class I maser transitions. Thermal methanol emission in this source is confined to a central hot core, while the three class I maser transitions are detected in two additional regions. These two maser-only emission regions are clearly associated with shocked gas traced by 2 <jats:italic>μ</jats:italic>m <jats:italic>Ks</jats:italic>-band and thermal <jats:italic>v</jats:italic> = 0, <jats:italic>J</jats:italic> = 5−4 SiO molecular emission. In contrast to the thermal methanol emission from the hot core, the three class I maser transitions show an positive trend in the rotation diagram for the two maser regions. Large velocity gradient modeling of the 266.8, 218.4, and 229.7 GHz transitions shows that the 266.8 GHz transition can be a maser for a wide range of conditions. The intensity ratios for the three methanol transitions detected in maser regions can be reproduced under conditions that are typical for class I methanol maser sites. These facts all support the hypothesis that the detected emission from the 266.8 GHz methanol (5<jats:sub>2</jats:sub>−4<jats:sub>1</jats:sub> <jats:italic>E</jats:italic>) transition is masing.</jats:p>
