The light curve of the Type Ia supernova SN 1895B (in NGC 5253) is important because Sandage et al. have measured a distance to the host galaxy by means of Cepheid variables and thus have derived the Hubble constant. However, the last time the supernova plates were measured was in 1923, and the resultant photometry is inconsistent at the 0.8 mag level. In this paper, I report on the results of my remeasurement of the old supernova plates with a scanning microdensitometer. I find B-magnitudes of…

The Peak Brightness of SN 1974G in NGC 4414 and the Hubble Constant

The light curve of the Type Ia supernova SN 1974G (in NGC 4414) is important because the Hubble Space Telescope has measured the distance to the host galaxy by means of Cepheid variables, and thus…

Cepheid Calibration of the Peak Brightness of Type Ia Supernovae. VIII. SN 1990N in NGC 4639

Repeated imaging observations have been made of NGC 4639 with the Hubble Space Telescope between 1995 April and July over an interval of 71 days. Images were obtained on 12 epochs in the F555W band…

Maximum Luminosities of Type Ia Supernovae from Cepheid Distances and the Value of H o

Supernovae of type Ia, with neutral colors (B - V ≃ 0.0),are the best standard candles known. They define at maximum light a tight, perfectly linear Hubble diagram out to 30 000 km s-1. Therefore the…

Cepheid Calibrations from the Hubble Space Telescope of the Luminosity of Two Recent Type Ia Supernovae and a Redetermination of the Hubble Constant

We report observations of two nearby Type Ia supernovae (SNe Ia) for which observations of Cepheid variables in the host galaxies have been obtained with the Hubble Space Telescope: SN 1994ae in NGC…

Type ia supernovae as extragalactic distance indicators

Because Type Ia supernovae (SNe Ia) are not perfect standard candles, it is important to be able to use distance–independent observables (DIOs) to define subsets of SNe Ia that are “nearly standard…

Thirty Years of Radio Observations of Type Ia SN 1972E and SN 1895B: Constraints on Circumstellar Shells

We have imaged 35 yr of archival Very Large Array observations of the nearby (dL = 3.15 Mpc) Type Ia supernovae SN 1972E and SN 1895B between 9 and 121 yr post-explosion. No radio emission is…

Distance Scale from Supernovae

Supernovae have been playing an ever increasing role in the determination of the key cosmological parameters. They are extremely luminous point sources whose brightness at maximum rivals that of…

All known hot RCB stars are fading fast over the last century

The R Coronae Borealis (RCB) stars are cool supergiants that display irregular and deep dips in their light curves, caused by dust formation. There are four known hot RCB stars (DY Cen, MV Sgr, V348…

The historical 1900 and 1913 outbursts of the binary blazar candidate OJ287

We report on historical optical outbursts in the OJ287 system in 1900 and 1913, detected on archival astronomical plates of the Harvard College Observatory. The 1900 outburst is reported for the…

The Peak Brightness of SN1937C in IC4182 and the Hubble Constant

The light curve of the Type Ia supernova SN 1937C (in IC 4182) is important because Sandage et al. have measured a distance to the host galaxy by means of Cepheid variables and thus have derived the…

THE PHOTOMETRIC PROPERTIES OF THE BRIGHT TYPE I SUPERNOVA 1981B IN NGC 4536.

The U, B, V, and R light curves exhibit the typical forms of a Type I SN and suggest that the maximum occurred on JD2444672 when the SN was at Bmax = 12.00. The color indices (B-V) and (U-B) vary in…

Observations of the Hubble Space Telescope (HST) between 1993 May 31 and 1993 July 19 in 20 epochs in the F555W passband and five epochs in the F785LP passband have led to the discovery of 14…

The Peak Brightness of Supernovae in the U Band and the Hubble Constant

The peak magnitudes of Type I supernovae in the U band can be used to answer various questions relating to supernovae and the Hubble constant: (1) Well-observed normal Type Ia supernovae are placed…

THE INTRINSIC COLORS OF SUPERNOVAE OF TYPE IA

The absolute magnitudes derived for supernovae of type Ia in spiral galaxies depend critically on their assumed intrinsic colors. For 14 SNIa in spirals (and an assumed Hubble parameter of 75 km s-1…
