Would the sun be more luminous if it had the same surface temperature but were more massive?

Yes, it probably would because there would be more light coming off it.

What is the surface temperature of Draco the constellation?
each different star in the constellation (there are 13) would have a different surface temperature, which is based on what phase of stellar life they are in and how massive they are
How can a cool star be more luminous than a hot star?
Luminosity is related to temperature and distance.A cool and thus less luminous star would be brighter than a more luminous star at a greater distance.Our Sun is a relatively cool star in comparison to say Rigel, but because it is closer it appears more luminous and brighter.
Why is Betelgeuse cool but gives off massive amounts of light?
When talking about stars, "cool" is a relative term. Betelgeuse has a variable surface temperature of 5,200 to 6,100 degrees Fahrenheit. Such a temperature may seem extremely hot to us and is easily hot enough to emit bright light but it is fairly cool as stars go. The comparatively low temperature of Betelgeuse means that it gives off less light per square meter than a hotter star would, but it makes up for it with its massive size, more than 900 times the diameter of the sun. As massive size means a large surface are and thus a huge output of light.
On what planet will lead melt?
Lead and several other substances would melt on the surfaces of Mercury and Venus. Mercury's mean surface temperature: 167oC (333oF) Venus' mean surface temperature: 464oC (867oF)
What does luminous object contain?
Self-illuminating would be phosphorous.

What is the temperature of night on Saturn?
Saturn is the gas Giant with tiny core deep down the atmosphere. Surface temperature of Saturn is govern by its' thermodynamic cycle of rise and sink of massive gases. I believe, the surface temperature at the reference surface would not be of any great difference may be 10,000 oC with insignificant difference of day and night.
Which planet would you expect has the lowest surface temperature Uranus Saturn or Neptune?
The lowest surface temperature is Jupiter. 
What units would be used to measure the surface temperature of a plane?
Surface temperature is the temperature of a body at a particular location. Factors that affects this temperature are altitude, and environmental temperature. The surface temperature declines or goes up as the plane changes altitude.

How does a forest affect temperature?
The influence of a forest on temperature. The forest can lower the surface temperature on the surface during the season. The cool surface temperature allows for the growth of some vegetation that would not grow in the unprotected heat of the sun.
When a lamp is turned off is it luminous or non-luminous?
If the bulb is switched off, then we would call it non-luminous.
How would you expect the surface tension of water to be affected by increasing temperature?
surface tension of water is affected by temperature as it starts to evaporate when there is hot temperature but due to unnatural medium its surface starts to freeze when the temperature outside is cold,so this gives the reason that surface tension of water is affected by temperature.
What effect would thick cover have on the temperature of earths surface?
It would block out significant sunlight, lowering the temperature.
What effect would thick cloud have on the temperature of Earth's surface?
It would block out significant sunlight, lowering the temperature.
