EPJ Web of Conferences, 2011 It has been shown that an Earth-size planet or a super-Earth, in resonance with a transiting Jupiter-like body around an M star, can create detectable TTV signals (Kirste & Haghighipour, 2011).

Kepler-91b: a planet at the end of its life. Planet and giant host star properties via light-curve variations [PDF]
, 2013 The evolution of planetary systems is intimately linked to the evolution of their host star. Our understanding of the whole planetary evolution process is based on the large planet diversity observed so far.

Precise Age for the Binary Star System 12 Com in the Coma Berenices Cluster
The Astronomical Journal, 2023 We present measurements of the interferometrically resolved binary star system 12 Com and the single giant star 31 Com in the cluster Coma Berenices. 12 Com is a double-lined spectroscopic binary system consisting of a G7 giant and an A3 dwarf at the ...

Stellar loci IV. red giant stars [PDF]
Research in Astronomy and Astrophysics, 2021 Abstract In the fourth paper of this series, we present the metallicity-dependent Sloan Digital Sky Survey (SDSS) stellar color loci of red giant stars, using a spectroscopic sample of red giants in the SDSS Stripe 82 region. The stars span a range of 0.55 – 1.2 mag in color g – i, –0.3 – –2.5 in metallicity [Fe/H], and have values of ...

TU Tau B: The Peculiar “Eclipse” of a Possible Proto-barium Giant
The Astronomical Journal, 2023 TU Tau (=HD 38218 = HIP 27135) is a binary system consisting of a C-N carbon star primary and an A-type secondary. We report on new photometry and spectroscopy which tracked the recent disappearance of the A-star secondary.

Gaia17bpp: A Giant Star with the Deepest and Longest Known Dimming Event
The Astrophysical Journal, 2023 We report the serendipitous discovery of Gaia17bpp/2MASS J19372316+1759029, a binary star with a deep single large-amplitude dimming event of ∼4.5 mag that lasted over 6.5 yr.

The Global Evolution of Giant Molecular Clouds II: The Role of Accretion [PDF]
, 2011 We present virial models for the global evolution of giant molecular clouds. Focusing on the presence of an accretion flow, and accounting for the amount of mass, momentum, and energy supplied by accretion and star formation feedback, we are able to ...

Wobbling Jets in Common Envelope Evolution
The Astrophysical Journal, 2023 We find that the convective motion in the envelopes of red supergiant (RSG) stars supplies a non-negligible stochastic angular momentum to the mass that a secondary star accretes in a common envelope evolution (CEE), such that jets that the secondary ...
