A decade of radial-velocity monitoring of rho Leo: moment analysis and periodic variability
V. A. Checha, A. Aret, I. Kolka +6
We investigate the origin of long-term spectroscopic and photometric variability in the blue supergiant rho Leo, with particular emphasis on distinguishing between intrinsic pulsat…
TrES-1 b: A Case Study in Detecting Secular Evolution of Exoplanet Orbits
Simone R. Hagey, Billy Edwards, Angelos Tsiaras +43
We present a comprehensive analysis of transit, eclipse, and radial velocity data of the hot Jupiter TrES-1 b and confirm evidence of orbital variations on secular timescales. Appa…
A rare phosphorus-rich star in an eclipsing binary from TESS
Colin P. Folsom, Mihkel Kama, Tõnis Eenmäe +6
Context: Few exoplanets around hot stars with radiative envelopes have been discovered, although new observations from the TESS mission are improving this. Stars with radiative env…
The First Global e-Competition on Astronomy and Astrophysics
Ioana A. Zelko, Charles Barclay, Tonis Eenmae +7
The first Global e-Competition on Astronomy and Astrophysics was held online in September-October 2020 as a replacement for the International Olympiad on Astronomy and Astrophysics…
Near-infrared characterization of four massive stars in transition phases
Yanina R. Cochetti, Michaela Kraus, María L. Arias +5
Massive stars typically undergo short-lived post-main sequence evolutionary phases with strong mass loss and occasional mass eruptions. Many of such massive stars in transition pha…
Estimation of time delays from two blended light curves of gravitational lenses
A. Hirv, T. Eenmäe, L. J. Liivamägi +1
Long time photometric monitoring programs of gravitational lens systems are often carried on using modest equipment. The resolution of such observations is limited and some of the…
