Polarized, variable radio emission from the scallop-shell binary system DG CVn
Simranpreet Kaur, Daniele Viganò, Jackie Villadsen +9
DG CVn is an eruptive variable star and represents the closest member of the known sample of complex periodic variables, or scallop-shell stars. Over the years, this M dwarf binary…
Optical constraints on the coldest metal-poor population
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. Martín +10
The coldest metal-poor population made of T and Y dwarfs are archaeological tracers of our Galaxy because they are very old and have kept the pristine material. The optical propert…
Hints of auroral and magnetospheric polarized radio emission from the scallop-shell star 2MASS J050827292101444
Simranpreet Kaur, Daniele Viganò, Víctor J. S. Béjar +18
Scallop-shell stars, a recently discovered class of young M dwarfs, show complex optical light curves that are characterized by periodic dips as well as other features that are sta…
A young spectroscopic binary in a quintuple system part of the Local Association
Carlos Cardona Guillén, Nicolas Lodieu, Víctor J. S. Béjar +9
Double-lined spectroscopic binaries (SB2) allow us to determine a lower limit of the masses of their components directly to test stellar models. In this work, our aim is to derive…
Search for the sub-stellar lithium depletion boundary in the open star cluster Coma Berenices
Eduardo L. Martín, Nicolas Lodieu, Víctor Sánchez Béjar
We mainly aim to search for the lithium depletion boundary (LDB) among the sub-stellar population of the open star cluster Coma Berenices. We carried out a search for brown dwarf (…
First Detection of Two Superoutbursts during Rebrightening Phase of a WZ Sge-type Dwarf Nova: TCP J21040470+4631129
Yusuke Tampo, Kojiguchi Naoto, Keisuke Isogai +51
We report photometric and spectroscopic observations and analysis of the 2019 superoutburst of TCP J21040470+4631129. This object showed a 9-mag superoutburst with early superhumps…
