A blue depression in the optical spectra of M dwarfs
Hugh R. A. Jones, Yakiv Pavlenko, Yuri Lyubchik +3
A blue depression is found in the spectra of M dwarfs from 4000 to 4500A. This depression shows an increase toward lower temperatures though is particularly sensitive to gravity an…
A Roche Lobe-filling hot Subdwarf and White Dwarf Binary: possible detection of an ejected common envelope
Jiangdan Li, Christopher A. Onken, Christian Wolf +12
Binaries consisting of a hot subdwarf star and an accreting white dwarf (WD) are sources of gravitational wave radiation at low frequencies and possible progenitors of type Ia supe…
Ultra-luminous quasars at redshift from SkyMapper
Christian Wolf, Wei Jeat Hon, Fuyan Bian +6
The most luminous quasars at high redshift harbour the fastest-growing and most massive black holes in the early Universe. They are exceedingly rare and hard to find. Here, we pres…
Spectroscopic Observations of SN 2012fr: A Luminous Normal Type Ia Supernova with Early High Velocity Features and Late Velocity Plateau
M. J. Childress, R. A. Scalzo, S. A. Sim +55
We present 65 optical spectra of the Type Ia supernova SN 2012fr, of which 33 were obtained before maximum light. At early times SN 2012fr shows clear evidence of a high-velocity f…
