The light curve of SN 1572 is described in the terms used nowadays to characterize Type Ia supernovae (SNe Ia). By assembling the records of the observations done in 1572-1574 and evaluating their uncertainties, it is possible to recover the light curve and the color evolution of this supernova. It is found that within the SN Ia family, the event should have been an SN Ia with a normal rate of decline, its stretch factor being s ~ 0.9. The visual light curve near maximum, late-time decline, and…

The Light Curve and Distance of the Kepler Supernova: News from Four Centuries Ago
We study the light curve of SN 1604 using the historical data collected at the time of observation of the outburst. Comparing the supernova with recent SNe Ia of various rates of decline after
Tycho's Supernova: The View from Gaia
SN 1572 (Tycho Brahe’s supernova) clearly belongs to the Ia (thermonuclear) type. It was produced by the explosion of a white dwarf (WD) in a binary system. Its remnant has been the first of this
We present an analysis of the chemical abundances of the star Tycho G in the direction of the remnant of supernova (SN) 1572, based on Keck high-resolution optical spectra. The stellar parameters of
Tycho Brahe’s 1572 supernova as a standard type Ia as revealed by its light-echo spectrum
An optical spectrum of Tycho Brahe’s supernova near maximum brightness is obtained from a scattered-light echo more than four centuries after the direct light from the explosion swept past the Earth, finding that SN’1572 belongs to the majority class of normal type Ia supernovae.
The binary progenitor of Tycho Brahe's 1572 supernova
A survey of the central region of Tycho's supernova remnant, around the position of the explosion, finds a type G0–G2 star, similar to the authors' Sun in surface temperature and luminosity (but lower surface gravity), which appears to be the surviving companion of the supernova.
No hot and luminous progenitor for Tycho’s supernova
Type Ia supernovae have proven vital to our understanding of cosmology, both as standard candles and for their role in galactic chemical evolution; however, their origin remains uncertain. The
It is widely believed that Type Ia supernovae (SNe Ia) originate in binary systems where a white dwarf accretes material from a companion star until its mass approaches the Chandrasekhar mass and
The Origin of the Iron-Rich Knot in Tycho's Supernova Remnant
X-ray observations of supernova remnants (SNRs) allow us to investigate the chemical inhomogeneity of ejecta, offering unique insight into the nucleosynthesis in supernova explosions. Here we present
The End of Amnesia: A New Method for Measuring the Metallicity of Type Ia Supernova Progenitors Using Manganese Lines in Supernova Remnants
We propose a new method to measure the metallicity of Type Ia supernova progenitors using Mn and Cr lines in the X-ray spectra of young supernova remnants. We show that the Mn-to-Cr mass ratio in
Nearby Supernova Factory Observations of SN 2006D: On Sporadic Carbon Signatures in Early Type Ia Supernova Spectra
We present four spectra of the Type Ia supernova (SN Ia) 2006D extending from -7 to +13 days with respect to B-band maximum. The spectra include the strongest signature of unburned material at
